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 TestSpace
{
    class Test
    {
        static void Main(string[] args)
        {
            string[] arrRead;
            int i, j, k, l, N, z;
            N = int.Parse(Console.ReadLine());
            int[] intRead = new int[3];

            for (i = 0; i < N; i++)
            {
                arrRead = Console.ReadLine().Split(' ');

                for (j = 0; j < 3; j++)
                {
                    intRead[j] = int.Parse(arrRead[j]);
                }

                for (k = 0; k < 2; k++)
                {
                    for (l = 2; k < l; l--)
                    {
                        if (intRead[l] < intRead[l - 1])
                        {
                            z = intRead[l];
                            intRead[l] = intRead[l - 1];
                            intRead[l - 1] = z;
                        }                        
                    }
                }

                if (Math.Pow(intRead[0], 2) + Math.Pow(intRead[1], 2) == Math.Pow(intRead[2], 2))
                {
                    Console.WriteLine("YES");
                }
                else 
                {
                    Console.WriteLine("NO");

                }      
            }
        }
