Maximum Contiguous Sum Solution

Problem Statement

Given an array of integers `nums`, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.

Example 1
Input
nums = [-2, 1, -3, 4, -1, 2, 1, -5, 4]
Output
6

Explanation: The contiguous subarray [4, -1, 2, 1] has the largest sum = 6.

Constraints

  • 1 <= nums.length <= 10^5
  • -10^4 <= nums[i] <= 10^4
