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

int main(){
  char s[3];
  int a=0,b=0,c=0;
  int flag=0;
  for(int i=0; i < 3; i++){
    scanf("%c",&s[i]);
    if(a == 1 && s[i] == 'a'){
      flag = 1;
      break;
    }
    if(b == 1 && s[i] == 'b'){
      flag = 1;
      break;
    }
    if(c == 1 && s[i] == 'c'){
      flag = 1;
      break;
    }
    if(s[i] == 'a') a = 1;
    if(s[i] == 'b') b = 1;
    if(s[i] == 'c') c = 1; 
  }
  if(flag == 0){
    printf("Yes");
  }else{
    printf("No");
  }
}
