Problem:
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 ≤ 1,000

N ≤ 1,000

Output

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

Sample Input

3
4 3 5
4 3 6
8 8 8

Output for the Sample Input

YES
NO
NO

Solution in JAVA (judge verdict: Accepted)


import java.util.Scanner;

class Main {
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int a, b, c, n, temp;
		Boolean is_changed = true;
		n = in.nextInt();
		for (int i = 0; i < n; i++) {
			a = in.nextInt();
			b = in.nextInt();
			c = in.nextInt();
			while (is_changed == true) {
				is_changed = false;
				if (a > b) {
					temp = a;
					a = b;
					b = temp;
					is_changed = true;
				}
				if (b > c) {
					temp = b;
					b = c;
					c = temp;
					is_changed = true;
				}
			}
			if (a * a + b * b - c * c == 0) {
				System.out.println("YES");
			} else {
				System.out.println("NO");
			}
			is_changed = true;
		}
	}
