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<stdlib.h>
#include<string.h>

int main(void){
   char input[4];
   int a=0;
   scanf("%s",input);
   a += (strcmp("abc",input)==0)?1:0;
   a += (strcmp("acb",input)==0)?1:0;
   a += (strcmp("bac",input)==0)?1:0;
   a += (strcmp("bca",input)==0)?1:0;
   a += (strcmp("cab",input)==0)?1:0;
   a += (strcmp("cba",input)==0)?1:0;
   if (a==1){printf("Yes\n");}else{printf("No\n");}
  return 0;
}
