        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
