Count of subsequences whose product is a difference of square of two integers | Function to count the number of contiguous subsequences whose product can be expressed as square of difference of two integers.
Iterating through the array.
Check if that number can be expressed as the square of difference of two numbers.
Variable to compute the product.
Finding the remaining subsequences.
Check if that number can be expressed as the square of difference of two numbers.
Return the number of subsequences.
