题目描述
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 $a$ ?

输入格式
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.
输出格式
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.
输入输出样例
输入 #1
3 30 60 90
输出 #1
NO YES YES
说明/提示
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.
