    //You are given a sequence of N positive integer numbers and one binary digit B (0 or 1).
    //Your task is to write a program that finds the number of binary digits (B) in each of the N numbers in binary numeral system. Example: 20 in the binary numeral system looks like this: 10100. The number of binary digits 0 of the number 20 in the binary numeral system is 3.
