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 P0003_Is_it_a_Right_Triangle
{
    class Program
    {
        static void Main(string[] args)
        {

            List<string> lines = new List<string>();

            int cntLine = int.Parse(Console.ReadLine());

            for(int i = 1; i <= cntLine; i++)
            {
                lines.Add(Console.ReadLine());
            }          

            foreach (string line in lines)
            {
                List<string> sidesStr = line.Split(' ').ToList<string>();
                List<int> sides = new List<int>();

                foreach (string sideStr in sidesStr)
                {
                    sides.Add(int.Parse(sideStr));
                }

                sides.Sort();

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

            }


        }
