Can you provide a code to maximum product subset of an array and the other steps required given the following:
Maximum product subset of an array | Python3 program to find maximum product of a subset ..
Find count of negative numbers , count of zeros , negative number with least absolute value and product of non - zero numbers.
If number is 0 , we don 't  multiply it with product..
Count negatives and keep track of negative number with least absolute value ..
If there are all zeros.
If there are odd number of negative numbers.
Exceptional case : There is only negative and all other are zeros.
Otherwise result is product of all non - zeros divided by negative number with least absolute value.
Driver Code"
How can the above be solved in Python?
