Constraints

|S|=3

S consists of a, b and c.

Input

#include <stdio.h>
#include <stdbool.h>

bool tfjudge(char str[]){
    for(int i = 0; i < 3; i++){
        if(str[i] == 'a' ||str[i] == 'b' ||str[i] == 'c')
            return true;
    }
    return false;
}

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