Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

int main (int argc, char* argv[]) {
  char n[3];
  scanf("%s", n);

  for (int i = 0; i < 3; i++) {
    if (n[i] == '1') {
      n[i] = '9';
    } else if (n[i] == '9') {
      n[i] = '1';
    }
  }

  printf("%s\n", n);

  return 0;
