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;

namespace aoj
{
    class Program
    {
        static void Main()
        {
            var size = int.Parse(Console.ReadLine());
            var arr = new string[size];
            for (var i = 0; i < size; i++)
            {
                arr[i] = Console.ReadLine();
                var _ = arr[i].Split(' ');
                var num = new int[3];
                for (var j = 0; j < 3; j++)
                {
                    num[j] = int.Parse(_[j]);
                }
                if (num[0]*num[0] + num[1]*num[1] == num[2]*num[2] ||
                    num[1]*num[1] + num[2]*num[2] == num[0]*num[0] ||
                    num[2]*num[2] + num[0]*num[0] == num[1]*num[1])
                {
                    Console.WriteLine("YES");
                }
                else
                {
                    Console.WriteLine("NO");
                }
            }
        }
    }
