Given an array of integers nums, find the maximum length of a subarray where the product of all its elements is positive.

\n\n

A subarray of an array is a consecutive sequence of zero or more values taken out of that array.

\n\n

Return the maximum length of a subarray with positive product.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [1,-2,-3,4]\nOutput: 4\nExplanation: The array nums already has a positive product of 24.\n
\n\n

Example 2:

\n\n
\nInput: nums = [0,1,-2,-3,-4]\nOutput: 3\nExplanation: The longest subarray with positive product is [1,-2,-3] which has a product of 6.\nNotice that we cannot include 0 in the subarray since that'll make the product 0 which is not positive.
\n\n

Example 3:

\n\n
\nInput: nums = [-1,-2,-3,0,1]\nOutput: 2\nExplanation: The longest subarray with positive product is [-1,-2] or [-2,-3].\n
