Given an array \(A\) of \(N\) integers.
Find the count of subarrays whose product of elements is a perfect cube.
Input Format:
- First line contains an integer \(N\).
- Next line contains \(N\) space-separated integers denoting the array elements.
Output Format:
Print the number of subarrays whose product of elements is a perfect cube.
Constraints:
\(1 \le N \le 10^5\)
\(1 \le A[i] \le 10^2\)
Sample Input
4 2 4 6 36
Sample Output
3
Explanation
- Three subarrays with product of elements as a perfect cube are:
- \([2,4] \) product is \(8 (2^3)\)
- \([6,36]\) product is \(216 (6^3)\)
- \([2,4,6,36]\) product is \(1728(12^3)\)
