#include "iostream.h"

int countSetBits(int n) {
       int count = 0;
       while(n) {
               n = n & (n - 1);
               count++;
       }
       return count;
}

int main() {
       int n, m, b1, b2;
       cin >> n;
       for(int i = 1; i <= n; i++) {
               cin >> m;
               b1 = countSetBits(m);
               b2 = 0;
               while(m) {
                       b2 += countSetBits(m % 10);
                       m = m / 10;
               }
               cout << b1 << " " << b2 << endl;
       }
       return 0;
}
