I found an interesting problem on https://leetcode.com/problems/maximum-product-subarray/:
Given an integer array nums, find the contiguous subarray within an array (containing at least one number) which has the largest product.

Example 1:

Input: [2,3,-2,4]
Output: 6
Explanation: [2,3] has the largest product 6.

Example 2:

Input: [-2,0,-1]
Output: 0
Explanation: The result cannot be 2, because [-2,-1] is not a subarray.

I tried it in Python, but could not do it. Can you solve it?

Give me a Python program to find the contiguous subarray within an array (containing at least one number) which has the largest product?
