Maximum subarray sum The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: max_sequence([-2, 1, -3, 4, -1, 2, 1, -5, 4]) #…
dp[i] represents the maximum sum of subarray which ends in nums[i], and dp[i] = Math.max(nums[i], dp[i - 1] + nums[i]). and since we have to include nums[i] due to it’s on the defination of dp[i], and when dp[i-1]<0 we can just choose not to add it. so the...
