#include <stdio.h>

int main() {
    int h;
    double path, height;
    while (scanf("%d", &h) != EOF) { 
        height = (double) h;
        path = 0;
        path += height;
        for(int i = 1; i <= 5;i++)
        {
            path += height;
            height /= 2;
        }
        printf("%g\n", path - 2 * height);
        printf("%g\n", height);
    }
