#include <stdio.h>

int max(int *a, int *b)
{
    int swp;

    /*swap a <-> b.retain a > b-*/
    if (*a < *b)
    {
        swp = *b;
        *b = *a;
        *a = swp;
    }
    return 0;
}

int main()
{
    int Max = 0;
    int Senior = 0;
    int Minor = 0;
    int a, b, c;

    scanf("%d %d %d", &a, &b, &c);
    Max = a;
    Senior = b;
    Minor = c;
    max(&Max, &Senior);
    max(&Max, &Minor);
    max(&Senior, &Minor);
    printf("%d %d %d\r\n", Max, Senior, Minor);
    return 0;
