Return the number Objective: Find all contiguous subarrays that add up exactly to k and return their count. A subarray is a contiguous part of array, i. A continuous subarray is called nice if there are k odd numbers on it. Therefore, simultaneously update the count for both the indices. Intuitions, example walk through, and complexity analysis. To start with, let's Can we store the indices of odd numbers and for each k indices count the number of sub-arrays that contains them ? The count of contiguous subarrays that include index i is (i+1)* (N-i). A subarray of nums is called continuous if: * Let i, i + 1, , j be the indices in the So, we can iterate over arr [] while maintaining a hash map or dictionary to count the number of (prefix sum mod k).
