int main(void)
{
   char s[4];
   int i,a,b,ca=0,cb=0,cc=0;

   scanf("%s",s);
   for(i=0;i<3;i++){
      if(s[i]=='a') ca++;
      else if(s[i]=='b') cb++;
      else if(s[i]=='c') cc++;
      if((ca==2)||(cb==2)||(cc==2)){
         printf("No"); return 1;
      }
   }
   printf("Yes");
   return 0;
