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

                                    .Select(val => int.Parse(val))
                                    .ToArray();
            answers[i] = IsRightAngle(triangle) ? "YES" : "NO";
        }

    {
        Array.Sort(triangle);
        return Math.Pow(triangle[0], 2) + Math.Pow(triangle[1], 2) == Math.Pow(triangle[2], 2);
