Chef has an integer $N$. He knows that the factorial of a number $a$ is $a * (a - 1) * (a - 2) * . . . * 2 * 1$. Instead of finding the factorial of the interge $N$ that he has, he wants to find if there exists a number $M$ such that the factorial of $M$ is $N$. Help him find if there is a number $M$ such that $M!$ = $N$. Answer for $T$ test cases. ### Input - First line will contain $T$,
