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) {
int n = nums.length;
int max_temp = nums[0];
int min_temp = nums[0];
int result = nums[0];
for(int i=1;i<n;i++)
{
int a = nums[i]*max_temp; // 分为两种情况,正的最大和负的最小
int b = nums[i]*min_temp;
max_temp = Math.max(Math.max(a,b),nums[i]);
min_temp = Math.min(Math.min(a,b),nums[i]);
result = Math.max(max_temp,result);
}
return result;
}
}
