int main(void){
    int ans = 0;
    int num1 = 0,num2 = 0,num3 = 0;
    char s[4];
    scanf("%s",s);
    for(int i=0;i<3;i++){
        if(num1 = 0 && s[i]=='a'){
            ans++;
            num1++;
        }
        if(num2 = 0 && s[i]=='b'){
            ans++;
            num2++;
        }
        if(num3 = 0 && s[i]=='c'){
            ans++;
            num3++;
        }
    }
    if(ans==3){
        printf("Yes\n");
