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;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int a = int.Parse(Console.ReadLine());
            for (int b =0;b<a;b++)
            {
                int[] sss = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
                if (sss[0] * sss[0] + sss[1] * sss[1] == sss[2] * sss[2] || sss[0] * sss[0] + sss[2] * sss[2] == sss[1] * sss[1] || sss[1] * sss[1] + sss[2] * sss[2] == sss[0] * sss[0])
                    Console.WriteLine("YES");
                else
                    Console.WriteLine("NO");
            }

        }
    }
