WebJan 10, 2024 · A subarray is a contiguous part of array. An array that is inside another array. For example, consider the array [1, 2, 3, 4], There are 10 non-empty sub-arrays. The subarrays are (1), (2), (3), (4), (1,2), (2,3), (3,4), (1,2,3), (2,3,4) and (1,2,3,4). In general, for an array/string of size n, there are n* (n+1)/2 non-empty subarrays/substrings. WebNov 28, 2024 · The problem can be solved efficiently by using the prefix sum. Create two prefix sum arrays to store the sum of odd indexed elements and even indexed elements from the beginning to a certain index. Use them to get the sum of odd indexed and even indexed elements for each subarray. Follow the steps mentioned below to implement …
