#include <stdio.h>

int main(void){
    char str[3];
    int jud = 0;
    scanf("%s",str);
    for(int i = 0; i < 3; i++){
        if(str[i] == 'a'){
            jud++;
            for(int j = 0; j < 3; j++){
                if(str[j] == 'b'){
                    jud++;
                    for(int k = 0; k < 3; k++)
                        if(str[k] == 'c') jud++;
                }
            }
        }
    }
    if(jud == 3)
        printf("Yes");
    else
        printf("No");
