i) In sybarrays beginning with arr[i]. There are (n-i) such subsets. For example [2] appears in [2] and [2, 3]. ii) In (n-i)*i subarrays where this element is not first element. For example [2] appears in [1, 2] and [1, 2, 3]. Total of above (i) and (ii) =...
Java Finding a subarray with a given sum is a common problem that often appears in coding interviews and competitive programming. This problem can be solved using various techniques, each with its own trade-offs regarding time complexity and space complexity. In this article, we'll explore ...
