Time Complexity : O (n^2) Auxiliary space: O (1) Method 2 (Efficient): An efficient approach is to use the sliding window technique . This allows us to narrow down the search space and close in on the minimum largest sum that satisfies the splitting condition. Example 1: Input: N = 3 K = 2 Arr = {3,2,1} Output: 5 Explanation: The different subarray sums we can get from the array are = {6,5,3,2,1}. 1 m min(50,n) 1. Approach: It can be easily observed that for any subarray to have odd sum: Since only odd values can lead to odd sum, hence we can ignore the even values. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Sub-array A is greater than sub-array B if sum (A) > sum (B). We will process the elements in the array one by one. If the count of subarrays is more than sp, then increase the value of the left boundary.
