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.

public class Solution {
	public int maxSubArray(int[] A) {
		int max = A[0];
		int[] sum = new int[A.length];
		sum[0] = A[0];
 
		for (int i = 1; i < A.length; i++) {
			sum[i] = Math.max(A[i], sum[i - 1] + A[i]);
			max = Math.max(max, sum[i]);
		}
 
		return max;

function max(arr){
  let currentMax = null;
  let currentSection = null;
  for (let idx = 0; idx  a+b, 0);
      if(newMax > currentMax) {
        currentMax = newMax;
        currentSection = newSection;
      }
    }

  }
  return currentSection;
