#include <stdio.h>
#include <stdbool.h>

char count[256];

int main() {
  char *a, *b;
  scanf("%s %s", &a, &b);
  for (int i = 0; i < strlen(a); i++)
    count[a[i]]++;
  for (int i = 0; i < strlen(b); i++)
    count[b[i]]++;
  bool flag = true;
  for (int i = 0; i < 256; i++)
    if (count[i] != 0) flag = false;
  if (flag)
    printf("unique");
  else
    printf("not unique"); 
}
