Example 1: example-1 A Simple solution is to run two loop to split array and check it is possible to split array into two parts such that sum of first_part equal to sum of second_part. Interview prep doesn't have to be. Now we will find the minimum of (sum of g2, sum of g4, sum of g6, sum of g8, sum of g10). Split n into maximum composite numbers 2035. Partition Array Into Two Arrays to Minimize Sum Difference Finally print the largest divisible subset. Problem of Day Solution (13-dec-2022) (GFG) class Solution: def splitArray (self, arr, N, K): a,b = max (arr), sum (arr) while a < b: mid = (a + b) // 2 cursum, count = 0, 0 for num in arr: cursum += num if cursum > mid: cursum = num count += 1 if count >= K: a = mid + 1 else: b = mid return b. Hence, we need to use partition 4 to get the minimum among the largest sum of the subarrays.
