Solve the programming task below in a Python markdown code block.
Problem

One day, mo3tthi and tubuann decided to play a game with magic pockets and biscuits.
Now there are $ K $ pockets, numbered $ 1,2, \ ldots, K $.
The capacity of the $ i $ th pocket is $ M_i $, which initially contains $ N_i $ biscuits.
mo3tthi and tubuann start with mo3tthi and perform the following series of operations alternately.


* Choose one pocket.
* Perform one of the following operations only once. However, if the number of biscuits in the pocket selected as a result of the operation exceeds the capacity of the pocket, the operation cannot be performed.
* Stroking the selected pocket. Magical power increases the number of biscuits in your chosen pocket by $ 1 $.
* Hit the selected pocket. The number of biscuits in the pocket chosen by magical power is doubled by $ 2 $.



The game ends when you can't operate it, the person who can't operate loses, and the person who doesn't can win.
You, a friend of mo3tthi, were asked by mo3tthi in advance if you could decide if you could win this game.
For mo3tthi, make a program to determine if mo3tthi can definitely win this game.

Constraints

The input satisfies the following conditions.

* $ 1 \ leq K \ leq 10 ^ 5 $
* $ 1 \ leq N_i \ leq M_i \ leq 10 ^ {18} $
* All inputs are integers

Input

The input is given in the following format.


$ K $
$ N_1 $ $ M_1 $
$ \ vdots $
$ N_K $ $ M_K $


Output

When mo3tthi acts optimally, "mo3tthi" is output on one line if he can win, and "tubuann" is output otherwise.
