#include <stdio.h>

void f(char s[]) {
  int i;
  for (i = 0; i < 5; i++) printf("%c", s[i]);
  printf(" ");
  for (i = 6; i < 13; i++) printf("%c", s[i]);
  printf(" ");
  for (i = 14; i < 19; i++) printf("%c", s[i]);
  printf("\n");
}

int main(void) {
  char s[19];
  scanf("%s", s);
  f(s);
  return 0;
