#include <bits/stdc++.h>
using namespace std;

int main(){
  string s;
  bool d,e,f;
  cin >> s;

  for(int i=0; i<s.size(); i++){
    if(s.at(i) == 'a')    d = true;
    
    if(s.at(i) == 'b')      e = true;
    
    if(s.at(i) == 'c')      f = true;

  }
    if ( d == e == f) cout << "Yes" <<endl;
    else cout << "No" << endl;
    
  

  return 0;
