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[] nums) {
if (nums == null || nums.length == 0) {
return 0;
}
int max = nums[0];
int min = nums[0];
int res = nums[0];
int maxEnd = 0;
int minEnd = 0;
for (int i = 1; i < nums.length; i++) {
maxEnd = max * nums[i];
minEnd = min * nums[i];
max = Math.max(Math.max(maxEnd, minEnd), nums[i]);
min = Math.min(Math.min(maxEnd, minEnd), nums[i]);
res = Math.max(max, res);
}
return res;
}
}
