Maximum Subarray - Leetcode Solution

#cpp #leetcode

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

A subarray is a contiguous part of an array.

We need to use Kadane's Algorithm here

//Kadane's Algorithm

class Solution {
public:
    int maxSubArray(vector<int>& nums) {
        int ans =INT_MIN,sum =0;
        int n=nums.size();
        for(int i=0;i<n;++i){
           sum+=nums[i];
           ans = max(ans,sum);
        if(sum<0)
            sum=0;

        }
        return ans;

        }      

};
