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 C# (judge verdict: Accepted)

using System;

public class Test
{
	public static void Main()
	{
        var n=int.Parse(Console.ReadLine());
        for (int i=1; i<=n; ++i)
        {
            string[] input=Console.ReadLine().Split(' ');
            var a = int.Parse(input[0]);
            var b = int.Parse(input[1]);
            var c = int.Parse(input[2]);
            if ((-(a*a)+(b*b)+(c*c))*((a*a)-(b*b)+(c*c))*((a*a)+(b*b)-(c*c)) == 0)
            {
                Console.WriteLine("YES");
            }
            else
            {
                Console.WriteLine("NO");
            }
        }
	}
}
