Maximum Subarray

Find the contiguous subarray within an array (containing at least one number) which has the largest sum.

For example, given the array [?2,1,?3,4,?1,2,1,?5,4],
the contiguous subarray [4,?1,2,1] has the largest sum = 6.

#include<stdio.h>

int maxSubArray(int A[], int n) {
    int i,sum=0,max=A[0];
    for(i=0;i<n;i++){
        sum=sum+A[i];
        if(sum>max) max=sum;
        if(sum<0) {
            sum=0;
        }
    }
    return max;
}

void main(){
    int a[]={-2,1,-3,4,-1,2,1,-5,4};
    printf("%d\n",maxSubArray(a,9));
}
