Describe

Enter an array of positive integers a[0], a[1], a[2], ..., a[n-1], and calculate the sum of their binary low 3-bit.

#include <iostream> #include <vector> #include <algorithm>using namespace std;//here to complement your code int main ( int argc, char* argv[]) {        int V, my_sum=0;        Vector<int> Vec;        cin>>v;        while (v) {                vec.push_back (v);                cin>>v;        }        For_each (Vec.begin (), Vec.end (), Cmy_add (My_sum));        cout<<my_sum<<endl;        return 0;}

Input

Array A, which indicates the end of the input as 0.

Output

An integer that is the sum of the binary low 3 bits of each element of the input array.

Sample input

1 3 9 7 3 6 20 15 18 17 4 8 18 0

Sample output
