#include <iostream>
using namespace std;
int main()
{
    char c;
    int ans = 0;
    for(int i = 0; i < 3; i++){
        cin >> c;
        if('a' <= c && c <= 'c'){
            if(c == 'c') ans += 10;
            else         ans += c - 'a';
        }
    }
    if(ans == 11) cout << "Yes" << endl;
    else          cout << "No"  << endl;
    return 0;
