We know that prime numbers are positive integers that have exactly two distinct positive divisors. Similarly, we'll call a positive integer t Т-prime, if t has exactly three distinct positive divisors.You are given an array of n positive integers. For each of them determine whether it is Т-prime or not.

A permutation of length n is an integer sequence such that each integer from 0 to (n - 1) appears exactly once in it. For example, sequence [0, 2, 1] is a permutation of length 3 while both [0, 2, 2] and [1, 2, 3] are not.A fixed point of a function is a point that is mapped to itself by the function. A permutation can...

["NO", "YES", "NO"]
NoteIn the first sample test, despite the fact that there are substrings "AB" and "BA", their occurrences overlap, so the answer is "NO".In the second sample test there are the following occurrences of the substrings: BACFAB.In the third sample test there is no substring "AB" nor substring "BA".

In 2013, the writers of Berland State University should prepare problems for n Olympiads. We will assume that the Olympiads are numbered with consecutive integers from 1 to n. For each Olympiad we know how many members of the jury must be involved in its preparation, as well as the time required to prepare the problems...
