<div class="textblock"><p><a href="https://en.wikipedia.org/wiki/Subset_sum_problem" target="_blank">Subset-sum</a> (only continuous subsets) problem </p>
<p>We are given an array and a sum value. The algorithms find all the subarrays of that array with sum equal to the given sum and return such subarrays count. This approach will have \(O(n)\) time complexity and \(O(n)\) space complexity. NOTE: In this problem, we are only referring to the continuous subsets as subarrays everywhere. Subarrays can be created using deletion operation at the end of the front of an array only. The parent array is also counted in subarrays having 0 number of deletion operations.</p>
