Maximum Subarray
Detailed guide and Python implementation for the 'Maximum Subarray' problem.
Problem Statement
Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.
Write a function maxSubArray(nums: List[int]) -> int.
- •1 <= len(nums) <= 10^5
- •-10^4 <= nums[i] <= 10^4
Examples
nums = [-2,1,-3,4,-1,2,1,-5,4]
6
[4,-1,2,1] has the largest sum = 6.
nums = [1]
1
[1] has the largest sum = 1.
