NASM 32-bit Assembly Language for program:

You are to read in N integers, terminated by entering zeroes two times in a row. (These two zeroes will not be counted.) Write a program which will determine the number of positive, negative and zero numbers in the numbers that have been read in. Negative numbers can always be discerned because their most significant bit will be 1. Numbers that are zero have all bits equal to 0. Positive numbers are those in which the most significant bit is 0, but not all bits are.
