 » 6 days ago, # |   +164 Why Hello is 안녕하세요 but Codeforces is 코드포스 which is shorter than Hello?
•  » » 6 days ago, # ^ |   +60 Also thought how difficult is it to write just "Hello", just unbelievable
•  » » 6 days ago, # ^ |   +58 That's not even a Hello.It's a Hi. XD!
•  » » » 5 days ago, # ^ |   +10 The other side is that Hi is longer than Hello! xD여보세요 : Hello안녕하세요 : HiGoogle Translate
•  » » » » 5 days ago, # ^ | ← Rev. 2 →   0 And 'Hello' can be used as both '여보세요' and '안녕하셰요' in my country, so It is also able to say the length of 'Hello' and 'Hi' is equal. :)

•  » » 6 days ago, # ^ |   +25 I have always wondered how Chinese/Korean people write things
•  » » » 6 days ago, # ^ | ← Rev. 2 →   +34 That's an art :D(However I have not mastered it yet. T_T)
•  » » » 6 days ago, # ^ |   +93 It is actually very simple. We have these Oriental supernatural psychic abilities to inscribe complex letters into paper without using hands.
•  » » » 5 days ago, # ^ |   +11 I wonder how Arabs too
•  » » » » 5 days ago, # ^ |   0 Nope writing Arabic is easy.Arabic alphabets are simple in shape.
•  » » » » 5 days ago, # ^ |   +2 No, I'm Iranian and our font, Persian or Farsi is like Arabic. I think it is easy. :DMaybe these different opinions are because of different viewpoints. For us Korean or Chinese are hard to understand. But now I see that you think Arabic is difficult. Because we all are used to our own languages and other ones seem strange. But the most important think is that all languages are beautiful. :DSorry for my bad English. :DBtw do you Korean think your language is hard? Maybe I'm wrong.
•  » » » » » 5 days ago, # ^ |   0 Though I write Chinese since I born, I still think writing it is a exhausting job, lol.
•  » » » » » 5 days ago, # ^ |   +39 Korean letter seems scary because one syllable is cracked into a single letter. However, it's actually a composition of consonant letters (ㄱㄴㄷㄹㅁㅂㅅㅇㅈㅊㅋㅍㅌㅎ) and vowel letters (ㅏㅑㅓㅕㅗㅛㅜㅠㅡㅣ). So while there are 11172 Korean letters, you only have to remember 24 simple letters- after then you can write all of them!Korean people are proud of their language, and we have a "language day" which recently became a holiday. I also think this unique system makes pronunciation much clearer and complete. However, I'm not sure if it's easy, because "easy language" and "easy letters" are a different matter, and "smart letters" and "easy letters" also are. It's my mother tongue, so at least I'm not the one to judge.
•  » » » » » » 5 days ago, # ^ |   +3 Nicely said!
•  » » 6 days ago, # ^ |   +12 Technically it's Annyeonghaseyo XD
•  » » 6 days ago, # ^ |   +36 let's hope problems statements are long in Korean
•  » » 3 days ago, # ^ | ← Rev. 2 →   0 Well, if you use hanja honyong(漢字混用) to write 안녕하세요, the meaning of the phrase would be clearer (especially for Chinese). 안녕하세요=安寧하세요, it's asking if someone is free from worry. And, 코드포스=Kodeuposeu. This word is just a transliteration.

•  » » 5 days ago, # ^ |   +1 Absolutely
•  » » 5 days ago, # ^ |   0 Yes, of course

 » 5 days ago, # |   +15
 » 5 days ago, # |   +6 What an amazing implementation contest!
 » 5 days ago, # |   +13 In D why answer is not center of tree ?
•  » » 5 days ago, # ^ | ← Rev. 2 →   +5 check a look:41 2 2 33 4
•  » » 5 days ago, # ^ |   +8 Try this case: --- 8 2 1 1 3 3 4 4 5 1 6 6 7 7 8 --- The only answer is $2$.
•  » » » 5 days ago, # ^ |   0 so if the answer is not the center, then it must be one of the leaves right ? How to check that ?
•  » » » » 5 days ago, # ^ |   0 Suppose $v$ is not a center and not a leaf, then there are two leaves $l$ and $m$ at different distances from $v$ (suppose $l$ is closer). Consider the vertices at the same distance from $v$ as $l$ and notice that some of them are not leaves.
•  » » » » » 5 days ago, # ^ |   0 Ok thanks but I know how to prove that. What I want to ask is that if it is not the center, how could we find the leave which is the answer ?
•  » » » » 5 days ago, # ^ |   0 I tried to find centroid on slightly modified graph(I deleted chains starting from leaf nodes) I was late for about 30 sec to submit
 » 5 days ago, # |   0 How to approch E ?
•  » » 5 days ago, # ^ | ← Rev. 2 →   +6 The powers of f3, f2, f1 were terms of different tribonacci sequences with different first numbers. I couldnt figure out the sequence of powers of c, and it was also not there in OEIS :(Matrix Exponentiation is must, but couldnt figure out the matrix for c :'(
•  » » » 5 days ago, # ^ |   +6 Yeah, same ... wasn't able to figure out powers of c. Didn't know about OEIS though. Thanks for that :D
•  » » » » 5 days ago, # ^ |   -20 If you make $n=n-3$, then powers of c would be $2*\sum_{i=1}^n i = \frac{ n*(n+1) } {2}$
•  » » » 5 days ago, # ^ | ← Rev. 2 →   +3 You could reduce the problem to solving $G_{x} = G_{x-1}*G_{x-2}*G_{x-3}$, if you take $G_{x} = c^x F_{x}$. But, I couldn't see the fibonacci thing lol. Maybe we should have given the contest together xD.
•  » » » 5 days ago, # ^ |   0 Power for c was (n-2)*(n-3) using summation of AP formed: 2*(1+2+....(n-3)).
•  » » 5 days ago, # ^ | ← Rev. 2 →   +6 The answer is some power of $f_1,f_2,f_3,c$To deal with the power of $f_1,f_2,f_3$ it is a three-term recursion.(Fibonacci number is a two-term one). It can be rewritten in matrix form, and use fast power for large power.To deal with $c$ it is 2* A062544 in OEIS? It has a closed matrix form and solve it similar to the first one.Update 1 : Check tutorial/other stuff for better calculation of c
•  » » 5 days ago, # ^ |   0 Let g(x) = logc(f(x)) and h(x) = g(x) + x.The original equation becomes h(x) = h(x-1) + h(x-2) + h(x-3).After this, the problem could be solved by matrix power mod.
•  » » » 5 days ago, # ^ |   0 exponent " c " can be attached with f(X) to make it g(x) = (c^x)*f(x) ;
•  » » » » 5 days ago, # ^ |   +3 Yes. They look equivalent. I guess I am just not very comfortable with exponents.
•  » » » » » 4 days ago, # ^ |   0 I looked at your code https://codeforces.com/contest/1182/submission/55452776However, I was unable to understand the last 3 lines : ans = mul(ans, pow_mod(C, (3 * ll(a) + 2 * b + c) % (MOD - 1))); n %= (MOD - 1); ans = mul(ans, pow_mod(C, (MOD - 2) * n % (MOD - 1))); It would be great if someone could explain them!
•  » » » » » » 4 days ago, # ^ | ← Rev. 2 →   +1 Suppose after solving $h_x = h_{x-1} + h_{x-2} + h_{x-3}$ we end up with something like: $h_n = u\cdot h_3 + v\cdot h_2 + w\cdot h_1$.Therefore, $f_n = f_{3}^{u} \cdot f_2^{v} \cdot f_1^{w} \cdot C^{3u + 2v + w} \cdot C^{-n}$By Fermat's little theorem, we can take the reminder of the exponents mod $(MOD-1)$ to simplify the calculation.I hope this explains.

 » 5 days ago, # |   +3 how to solve C ??
•  » » 5 days ago, # ^ |   0 sorting first by the number of vowels, then alphabetically, on the one that ends, and then we create two arrays and run by the sorted, we look at the neighbors, if the letters are 2 words, then we sort again and see if the number of letters is equal, then it is 1 word. sorry, i don't know English very well.

 » 5 days ago, # |   +48 Shitty fast typing contest.
 » 5 days ago, # |   +55 I think in problem C finding m is enough and printing lyrics just makes problem complicated.
•  » » 5 days ago, # ^ |   -16 I dont think so, just create a map, work with indices and then print map[i], after finding M.
•  » » 5 days ago, # ^ |   +3 Yeah
•  » » 5 days ago, # ^ |   +2 yaa.... it's happened with me.
 » 5 days ago, # |   -6 How to solve E ??
 » 5 days ago, # |   +1 Any idea about pretest 16 in C? Is this logic wrong: For a given word,check if there is a word with same vowel count and same last vowel. If it isn't there,Try to check if there's something with same vowel count.
•  » » 5 days ago, # ^ |   +1 case: 4 a e e u
•  » » » 5 days ago, # ^ |   +4 holy crap. i should have run a pass first for finding all pairs with both vowel count and last vowel same,instead of doing both at the same time. changed that and your TC passes. Is this logic right? ^

 » 5 days ago, # |   +8 If honestly I don't understand. Pretests must be weak or this was just occasionally? I mean hacks like '.' and '*' and test 23 and so on. I understand that it is my fault but all in all pretests was too weak.
•  » » 5 days ago, # ^ | ← Rev. 2 →   +3 I asked them in the contest time about test only a * and they answered me its a invalid +, so if you were in doubt about this, you could have asked, even tho the pretest should have this test, I think.

All other cells are empty. Find out if the given picture has single "+" shape.This is what a + is, so, it s not obligated to have a + shape in the input, and that is why you have to code to find if there is only one + shape in the input, are you kidding me?

 » 5 days ago, # |   +10 In problem E, I am facing a doubt: I initially thought that I can condense the problem to the powers of f1,f2 and f3(ignore the c power for now). The powers of f1,f2 and f3 will be the nth, (n-1)th and (n-2)th term of Tribonacci sequence. But the powers will be in form of mod(10e9+7). As we know (a^b)mod M != (a^(b%M))%M ex: a=2,b=5,M=3, how do i effectively get the answer?
•  » » 5 days ago, # ^ |   +22 (a^b)mod M == (a^(b%(M-1)))%M for prime M, see Fermat's little theorem and Euler's theorem for general case.

The transfer matrix:0 0 1 0 01 0 1 0 00 1 1 0 00 0 1 1 00 0 0 1 1By using this,we can change [a,b,c,d,e] into [b,c,a+b+c+d,d+e,e]The formula of the power of c is f[i]=f[i-1]+f[i-2]+f[i-3]+2*i-6Let a=f[i-2],b=f[i-1],c=f[i],d=2*i-6,e=2So now we can transfer it.The initial matrix is [0,0,0,2,2],because f[1]=f1*(c^0),f[2]=f2*(c^0),f[3]=f3*(c^0).

Now, if vertex with maximum depth is unique, lets check it.After, we need find one vertex with degree greater then 2 (it is always exist because of quantity of the leaves). Run bfs2 from it.////Let's define nearest vertex with degree greater then 2 for current vertex like a good.In this bfs, we need mark all vertexes by the pairs = {distance(current vertex, good vertex), index of the good vertex}.It easy to proof, that if answer is possible, than there is only one leaf with unique pair {distance to its good vertex, quantity of leaves that correspond for this good vertex}. Now we just need to check this leaf.code: 55487910

# Find solution with initial value

### invisible_man

y'' - ty' + y = 1, y(0) = 1, y'(0) =2

I'm trying to solve by Laplace Transform and I got stuck at the end.Anyone can help me to solve it?

2. Apr 27, 2010

### matematikawan

Did you compute the Laplace transform of ty'(t) correctly? I think the Laplace transform of this term and computing the Laplace inversion later are the only diffuculty that I foresee.

3. Apr 27, 2010

### invisible_man

The Laplace Transform of ty' = -L[y]'

4. Apr 27, 2010

### matematikawan

I think so. Except that the RHS differentiation is wrt s, i.e. $$-\frac{dF}{ds}= -\frac{d}{ds}(sY-1)$$

### kosovtsov

Your ODE is not an ODE with constant coefficients, so it can not be solved by Laplace Transform.

An integrating factor to your ODE

$$\mu=t\exp(-\frac{t^2}{2})$$

and corresponding first integral is

$$I=\exp(-\frac{t^2}{2})(t\frac {d y}{d t}-y+1)+C1$$

in sense that

$$\frac {d I}{d t}=t\exp(-\frac{t^2}{2})(\frac {d^2 y}{d t^2}-t\frac {d y}{d t}+y-1),$$

what is equivalent to your ODE.

Substituting $$t=0$$ in $$I$$ we get

$$-y(0)+1=C1$$

and as $$y(0)=1$$ then

$$C1=0.$$

Now you have to solve first order ODE ($$I=0$$)

$$t\frac {d y}{d t}-y(t)+1=0.$$

Its solution is

$$y(t) = tC2+1$$

$$y(t) = 2t+1$$

### matematikawan

Some linear DE with variable coefficients can be solve via Laplace transform. It all depends on whether we can solve for Y(s) and later invert it. In this particular case, the transformed equation will be a linear first order DE in Y(s) which I think can be solve for Y(s) quite easily. But whether it can be invert easily, need to look at the expression first.

7. Apr 28, 2010

### kosovtsov

Can you give an example, please?

8. Apr 28, 2010

### matematikawan

I remember some time ago somebody try to solve Bessel equation via Laplace transform.
But that person didn't proceed to see them through.

But for the Bessel equation of order zero, it can be done.
x2y''+xy'+x2y = 0
xy''+y'+xy = 0

Apply Laplace transform and solve for Y(s)
$$-\frac{d}{ds}(s^2Y-as-b) + sY-a-\frac{dY}{ds}$$

$$\frac{dY}{ds}=-\frac{sY}{s^2+1}$$

$$Y(s)=\frac{A}{\sqrt{s^2+1}}$$

The solution will be the inversion of Y(s).

Summary Introduction

To explain: The way that critical thinking helps an individual to evaluate claims in the media even if an individual is not a scientific expert on the issue.

Concept introduction: Psychology is the branch of science that incorporates the behavior, thought, emotion, personality, and motivation. Psychological studies mainly employed to improve mental disorder, self-help, and performance. It involves mainly for examining the mind of an individual and identifying the actions that influence an individual.

Explanation

Explanation:

If an individual is thinking in a smart way, then this is known as critical thinking. Evaluating the ideas with evidences is the major part of critical thinking. Critical thinking is exploring the idea, analyzing the idea, evaluating the evidences without assuming and concluding the ideas with false assumption. When evaluating media claims, follow the instructions given below:

• Identify the observed or experimental evidences.
• Check the analysis that whether the claims are based on scientific verdicts or not.
• Detect the cited experts and analyze their citations.
• Prepare the agenda and check for the previous publications.

Thus, by identifying and evaluating the ideas, there occur the positive approach towards the claims. Hence, critical thinking is mainly based on evidence instead of trusting to a person’s perception, which is often wrong.

# Determining whether a certain graph is planar

Consider a connected graph whose cycles have length at least 4, the maximum valence is 4, there are 2 vertices of valence 2 and 4 of valence 3. I would like to show graphs of this type are planar . I am not sure whether the result is true or not. I am essentially trying to show that any connected subgraph whose vertices have at least valence 2 satisfy $2V -4 \geq E$. You may also note that the two vertices of valence 2 are not connected by a single edge, in fact the two vertices are antipodal points of a 4 cycle.

-

With the information given, you can not guarantee planarity. One counter example would be a graph consisting of the complete bipartite graph $K_{4,4}$ (not planar) and any bipartite graph with two degree-2-vertices, four degree-three-vertices, and the remaining vertices degree 4, such that the degree-2-vertices are opposite in a $C_4$. If you want it connected, reroute a couple edges between the two parts, keeping all degrees the same, and keeping $K_{3,3}$ as a subgraph.
certainly. just start with a 4-regular bipartite graph with $2n$ vertices on each side, which contains a pair of vertices whose neighborhoods exact in exactly $2$ vertices. Delete $4$ edges (the edges incident to the symmetric difference of the two neighborhoods), and you are done. – Flo Pfender Mar 27 '13 at 2:27

# Continuous, bijective function from $f:[0,1)\to \mathbb{R}.$

Prove that there does not exist a continuous, bijective function $f:[0,1)\to \mathbb{R}.$

By contradiction I can assume a function exists, so that function is surjective, onto and continuous. And I know I need to use the intermediate value theorem but I can't create such a contradiction.

From the interaction in comments I think OP needs bit more elaboration on the hint by Asaf. I will however refrain from providing a complete solution.

Assume that there is a function $f$ defined on $[0, 1)$ which is continuous and a bijection from $[0, 1)$ to $\mathbb{R}$. It means that $f$ is one-one function in particular i.e $f(a) = f(b)$ implies $a = b$.

Next let's consider $f(0)$ and $f(1/2)$. Because $f$ is one-one we must have $f(0) \neq f(1/2)$.

Let's assume that $f(0) < f(1/2)$ (the case $f(0) > f(1/2)$ can be handled similarly). Now we need to prove that if $x \in (0, 1)$ then $f(0) < f(x)$. This is where you need to use IVT for continuous functions. You should be able to do this by following Asaf's comments. And then we know that $f(0)$ is the minimum value of $f(x)$ and hence the part $(-\infty, f(0))$ of $\mathbb{R}$ is not mapped by this function $f$ and thus $f$ is not onto $\mathbb{R}$.

The proof of $f(0) < f(x)$ for all $x \in (0, 1)$ proceeds as follows. Clearly $f$ is one-one so $f(0) \neq f(x)$. If $x = 1/2$ then we already know that $f(0) < f(1/2) = f(x)$. So let $x \neq 1/2$. If $f(0) > f(x)$ then $f(x) < f(0) < f(1/2)$ so that $f(0)$ lies between $f(x)$ and $f(1/2)$ and hence by IVT we have ..... (I hope OP will be able to complete the dots)

If $f(0) > f(1/2)$ then we can show that $f(x) < f(0)$ for all $x \in (0, 1)$ so that $f(0)$ is the maximum value of $f$ and again $f$ is not onto $\mathbb{R}$.

Another thing to note. There is nothing special in $1/2$ we have chosen above. It can be replaced by any number lying in $(0, 1)$.

HINT: Show that a continuous injection is either order preserving or order reversing.

• Hi Asaf, im not sure what you mean by order preserving. But is it okay if I do this? suppose there exists such a function. Let $x\in [0,1)$ such that $f(x) <f(0)$ thus $f(0) \in [f(x),f(1)]$ therefore there exists a $y$ such that $f(y) = f(0)$ which is a contradiction to one to one? Is that okay or can I not assume there exists $f(x) <f(a)$? – user104235 Nov 20 '13 at 2:07
• To expand a bit on Asaf's hint, a continuous one-one function is either strictly increasing or strictly decreasing, hence either $f(0)$ is a minimum or a maximum of $f$ and thus range of $f$ is not $\mathbb{R}$, but an interval with one end point included. – Paramanand Singh Nov 20 '13 at 5:30
• @ParamanandSingh So I cant do it that way since its not strictly increasing or decreasing. – user104235 Nov 20 '13 at 5:47
• @ParamanandSingh So I have this. $f([0,1/2])$ is equal to either $[f(0),f(1/2)]$ or $[f(1/2),f(0)],$ so assume it equals $[f(0),f(1/2)].$ What can I say about $f(3/4)$? It has to be greater than $f(1/2)$ right? – user104235 Nov 20 '13 at 6:19
• After Asaf's comments I think you must have got a clear idea of what needs to be done. What Asaf has shown in his comments is that "if a continuous function changes its direction of growth (like the graph rises and falls) then it will not be one-one". This is the crux of the solution. – Paramanand Singh Nov 20 '13 at 7:59

Let $f : [0,1) \rightarrow \mathbb{R}$ be a bijection. Then the restriction of $f$ to $(0,1)$ is a continuous bijection with range $\mathbb{R} - {f(0)}$ which is clearly disconnected but (0,1) is connected.

Since there are continuous bijections (even homeomorphisms) from $(0,1)$ to $\mathbb R$, it somehow must have to do with that $0$. Now, how do we use it?

One observation would be that such a map $f$ restricts to a continuous bijection from $(0,1)$ to $\mathbb R\setminus\{f(0)\}$, the real line without one point. Why can such a map not exist?

A different version of the same argument would be that for such a map $f$ there would have to be an $a\in(0,1)$ with $f(a)<f(0)$ and a $b\in(0,1)$ with $f(b)>f(0)$. Now, what would the intermediate value theorem tell us then, and how would that lead to a contradiction?

# How do you implicitly differentiate 3y + y^4/x^2 = 2?

Jul 7, 2016

$\frac{\mathrm{dy}}{\mathrm{dx}} = = \frac{2 {y}^{4}}{3 {x}^{3} + 4 x {y}^{3}}$

#### Explanation:

${\left(3 y + {y}^{4} / {x}^{2} = 2\right)}^{p} r i m e$

[ie differentiate wrt x]

$\implies \left(3 y\right) ' + \left({y}^{4} / {x}^{2}\right) ' = {\left(2\right)}^{p} r i m e$

$\implies 3 y ' + \left({y}^{4} / {x}^{2}\right) ' = 0 q \quad \triangle$

two of those are very easy. we'll do the middle one using the quotient rule separately

$\left({y}^{4} / {x}^{2}\right) '$

$= \frac{{\left({y}^{4}\right)}^{p} r i m e {x}^{2} - {y}^{4} {\left({x}^{2}\right)}^{p} r i m e}{{x}^{4}}$

$= \frac{4 {y}^{3} y ' {x}^{2} - {y}^{4} \left(2 x\right)}{{x}^{4}}$ which we stuff straight back into $\triangle$ to get

$3 y ' + \frac{4 {y}^{3} y ' {x}^{2} - {y}^{4} \left(2 x\right)}{{x}^{4}} = 0$

some algebra

$3 y ' {x}^{4} + 4 {y}^{3} y ' {x}^{2} - 2 x {y}^{4} = 0$

$3 y ' {x}^{3} + 4 {y}^{3} y ' x - 2 {y}^{4} = 0$

collecting $y '$ s together

$y ' \left(3 {x}^{3} + 4 x {y}^{3}\right) = 2 {y}^{4}$

$y ' = = \frac{2 {y}^{4}}{3 {x}^{3} + 4 x {y}^{3}}$
