#include <string.h>
char tab[4][15]={"bowl", "knife", "fork", "chopsticks"};
intmain()
{
    int n;
    char str[20];
    while (~scanf("%d%*c", &n))
    {
        while (n--)
        {
            scanf("%s", str);
            for (int i = 0; i < 4; i++)
            {
                if (!strcmp(str, tab[i]))
                    printf("%s ", str);
            }
        }
