Maximum Product Subarray
Find the contiguous subarray within an array (containing at least one number) which has the largest product.
For example, given the array [2,3,-2,4],
the contiguous subarray [2,3] has the largest product = 6.
public class Solution { public int maxProduct(int[] A) { if (A == null || A.length == 0) { return 0; } int max = A[0], min = A[0], result = A[0]; for (int i = 1; i < A.length; i++) { int temp = max; max = Math.max(Math.max(max * A[i], min * A[i]), A[i]); min = Math.min(Math.min(temp * A[i], min * A[i]), A[i]); if (max > result) { result = max; } } return result; }} 转载地址：http://enuni.baihongyu.com/
