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;
class main
{
    static void Main(string[] args)
    {
            string s = Console.ReadLine();
            if (s != null)
            {
                int n = int.Parse(s);
                for (int i = 1; i <= n; ++i)
                {
                string s2 = Console.ReadLine();

                    if (s2 != null)
                    {
                        string[] t = s2.Split(' ');
                        int[] a = new int[3];
                        a[0] = int.Parse(t[0]);
                        a[1] = int.Parse(t[1]);
                        a[2] = int.Parse(t[2]);

                        Array.Sort(a);
                        if ((a[2] * a[2]) == (a[1] * a[1] + a[0] * a[0]))
                        {
                            Console.WriteLine("YES");
                        }
                        else
                        {
                            Console.WriteLine("NO");
                        }
                    }
                }
            }
        //Console.ReadKey();
