### 問題

#### Is it a Right Triangle?

Write a program which judges wheather given length of three side form a right triangle. Print "YES" if the given sides (integers) form a right triangle, "NO" if not so.

#### Input

Input consists of several data sets. In the first line, the number of data set, N is given. Then, N lines follow, each line corresponds to a data set. A data set consists of three integers separated by a single space.

#### Constraints

1 ≤ length of the side ≤ 1000
N ≤ 1000

#### Output

For each data set, print "YES" or "NO".

### 解答

#include<iostream>
#include<algorithm>
using namespace std;

int main(){
int a[3];
int b;
cin >> b;
while(cin >> a[0] >> a[1] >> a[2]){
sort(a,a+3);
if(a[2]*a[2] == a[1]*a[1] + a[0]*a[0]){
cout << "YES" << endl;
} else {
cout << "NO" << endl;
}
}
return 0;
}


while(cin >> a[0] >> a[1] >> a[2]) という書き方が便利ですねよく分からんけど
