Given a positive integer N, find if it can be expressed as x^{y} where y > 1 and x > 0 and x and y both are both integers.

Example 1:
Input:
N = 8
Output:
1
Explanation:
8 can be expressed
as 2^{3}.

Example 2:
Input:
N = 7
Output:
0
Explanation:
7 can't be expressed
int the form x^{y}.

Your Task:
You don't need to read input or print anything. Your task is to complete the function checkPower() which takes an integer N and returns 1 if possible else, 0.

Expected Time Complexity: O(sqrt(N))
Expected Auxiliary Space: O(1)

Constraints:
1<= N <=10000
