Minimum sum of product of two arrays | Function to find the minimum product.
Find product of current elements and update result ..
If both product and b [ i ] are negative , we must increase value of a [ i ] to minimize result ..
If both product and a [ i ] are negative , we must decrease value of a [ i ] to minimize result ..
Similar to above two cases for positive product ..
Check if current difference becomes higher than the maximum difference so far ..
Driver function"
How can the above be solved in Python?
