Count of index pairs in array whose range product is a positive integer | Python3 program to find the count of index pairs in the array positive range product.
Condition if number of negative elements is even then increase even_count.
Otherwise increase odd_count.
Condition if current element is negative.
Condition if number of negative elements is even then add even_count in answer.
Otherwise add odd_count in answer.
