Write a function solution that, given an array A of Nintegers (between -100 and 100), returns the sign (-1,0, 1) of the product of all the numbers in the array multiplied together. Assume that N is between 1 and 1000. For example, given A = [1, -2, -3,5), the function should return 1 (the multiplication equals 30). Given A = [1,2,3, -5] your function should return -1 (the multiplication equals -30). Given A = [1, 2, 0, -5] your function should return 0 (the multiplication equals 0)
