Can you provide a code to length of longest subarray with positive product and the other steps required given the following:
Length of longest subarray with positive product | Function to find the length of longest subarray whose product is positive.
Stores the length of current subarray with positive product.
Stores the length of current subarray with negative product.
Stores the length of the longest subarray with positive product.
Reset the value.
If current element is positive.
Increment the length of subarray with positive product.
If at least one element is present in the subarray with negative product.
Update res.
If current element is negative.
Increment the length of subarray with negative product.
If at least one element is present in the subarray with positive product.
Update res.
Driver Code"
How can the above be solved in Python?

	arr = [ - 1 , - 2 , - 3 , 0 , 1 ]
	N = len ( arr )
	print ( maxLenSub ( arr , N ) )
