Emuskald needs a fence around his farm, but he is too lazy to build it himself. So he purchased a fence-building robot.
He wants the fence to be a regular polygon. The robot builds the fence along a single path, but it can only make fence corners at a single angle a.
Will the robot be able to build the fence Emuskald wants? In other words, is there a regular polygon which angles are equal to a?

Input
The first line of input contains an integer t (0 < t < 180) — the number of tests. Each of the following t lines contains a single integer a (0 < a < 180) — the angle the robot can make corners at measured in degrees.

Output
For each test, output on a single line “YES” (without quotes), if the robot can build a fence Emuskald wants, and “NO” (without quotes), if it is impossible.

Examples
Input

3
30
60
90

Output

NO
YES
YES

Note
In the first test case, it is impossible to build the fence, since there is no regular polygon with angle .
In the second test case, the fence is a regular triangle, and in the last test case — a square.

题意:判断输入的角度是否符合正多边形的角度。

思路:只需判断(360%(180-a))是否等于0即可。

AC代码

#include<iostream>
#include<algorithm>
#include<cstdio>
#include<cmath>
using namespace std;
int main()
{
    int t,a;
    cin>>t;
    while(t--)
    {
        cin>>a;
        if(360%(180-a)==0)printf("YES\n");
        else printf("NO\n");
    }return 0;
}
