int main(void){
    char s[3];
    int sc[3] = {0};
    scanf("%s",s);
    for(int i=0;i<3;i++){
        for(int j=0;j<3;j++){
            if(s[i] == 'a'+j)sc[j]++;
        }
    }
    for(int i=0;i<3;i++){
        if(sc[i] > 1){
            printf("No\n");
            return -1;
        }
    }
    printf("Yes\n");
    return 0;
