53. Maximum Subarray
On This Page
Given an integer array nums, find the subarray 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: [4,-1,2,1] has the largest sum = 6.
Example 2:
Input: nums = [1]
Output: 1
Example 3:
Input: nums = [5,4,-1,7,8]
Output: 23
Approach 1:
class Solution:
def maxSubArray(self, nums: List[int]) -> int:
max_ = nums[0]
max2 = nums[0]
if len(nums) == 1:
return max_
for i in range(1, len(nums)):
max_ = max(nums[i], nums[i] + max_)
max2 = max(max_, max2)
return max2
