Sign of the Product of an Array.cpp

/*


Solution By Rahul Surana


***********************************


There is a function signFunc(x) that returns:

1 if x is positive.
-1 if x is negative.
0 if x is equal to 0.
You are given an integer array nums. Let product be the product of all values in the array nums.

Return signFunc(product).
