Minimize sum of product of same-indexed elements of two arrays by reversing a subarray of one of the two arrays. Next largest is ‘y’ but that occurs 0 times in k so we will skip it. An efficient approach will be to find the divisors in O (sqrt n). Range query for Largest Sum Contiguous Subarray. Split the given array into K subarrays such that the maximum subarray sum achievable out of K subarrays formed is minimum. We can use hashmap to store the prefix sum, and if we reach any index for which there is already a prefix with same sum, we will find a subarray with sum as 0. I used a dfs on graph approach in. The idea is simple, we find all divisors of a number one by one. If “n != 1” , then a recursive call the function “largestSum” to find the largest sum of the subarray “arr [0…n-1]” excluding the last element “arr [n-1]”. Method 1 There can be two cases for the maximum sum: Case 1: The elements that contribute to the maximum sum are arranged such that no wrapping is there. Hence this is the valid answer. 2.
