Problem Statement

You are given a string S of length 3 consisting of a, b and c. Determine if S can be obtained by permuting abc.

Constraints

|S|=3

S consists of a, b and c.

Input

Input is given from Standard Input in the following format:

S

Output

If S can be obtained by permuting abc, print Yes; otherwise, print No.

Sample Input 1

bac

Sample Output 1

Yes

Swapping the first and second characters in bac results in abc.

Sample Input 2

bab

Sample Output 2

No

Sample Input 3

abc

Sample Output 3

Yes

Sample Input 4

aaa

Sample Output 4

No

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

#include <stdio.h>
#include <string.h>

int main(void){
  char s[4] = {'\0'};
  char cmp[4] = "abc";
  char temp;
  scanf("%3s", s);
  for(int i = 0; i < 3; i++){
    for(int j = i + 1; j < 3; j++){
      if(s[i] > s[j]){
	temp = s[i];
	s[i] = s[j];
	s[j] = temp;
      }
    }
  }

  if(strcmp(s, cmp) == 0) printf("Yes\n");
  else printf("No\n");

  return 0;
}
