Given Input is a list of integers with atleast 2 numbers in the input array. Write a function that returns maximum prduct value of not empty subset of those given numbers. \nNote: The product always consists of 2 or more given numbers from the list. All input values are integers\n\n```\neg.\n[0,3,-2,5] => "15"\n[0,0] => "0"\n[0,-1,1] => "0"\n[0,-1,-1] => "1"\n[0,0,1] => "0"\n[0,0,-1] => "0"\n```
