A semester in Chef's University has $120$ working days. The University's requirement is that a student should be present for at least $75\%$ of the working days in the semester. If not, the student is failed.

Chef has been taking a lot of holidays, and is now concerned whether he can pass the attendance requirement or not. $N$ working days have already passed, and you are given $N$ bits - $B_{1}$, $B_{2}$, ..., $B_{N}$. $B_{i}$ = $0$ denotes that Chef was absent on the $i^{th}$ day, and $B_{i}$ = $1$ denotes that Chef was present on that day.

Can Chef hope to pass the requirement by the end of the semester?

------ Input: ------

First line will contain $T$, the number of testcases. Then the testcases follow. 
Each testcase contains two lines of input.
The first line of each testcase contains a single integer, $N$, the number of days till now.
The second line of each testcase contains a string $B$ of length $N$ where $B_{i}$ represents the status of the $i^{th}$ day.

------ Output: ------
For each testcase, output the answer in a single line - "YES" if Chef can pass the attendance requirement and "NO" if not.

------ Constraints  ------
$1 ≤ T ≤ 10$
$1 ≤ N ≤ 120$
$0 ≤ B_{i} ≤ 1$

For Case 1, even if Chef attends all the remaining 70 days, he'll only have an attendance percentage of $70/120$ = $58.33\%$ which is less than $75\%$.

For Case 2, maximum attendance possible is $79.167\%$ which is more than $75\%$.

For Case 3, maximum attendance possible is $99.167\%$ which is more than $75\%$.
