3.6.9 게임 final  version 

 

우선 369게임 구현 

package com.example.coding.livefive;

public class TSNGameMain {

    public static void main(String[] args) {
        int n = 100;
        for (int i = 1; i <= n; i++) {
            System.out.println(do369(i));
        }
    }

    private static String do369(int i) {
        String number = String.valueOf(i);
        char[] chars = number.toCharArray();
        int clapCount = 0;
        for (char c : chars) {
            if (c == '3' || c == '6' || c == '9') {
                clapCount++;
            }
        }
        if (clapCount > 0) {
            return "clap";
        } else {
            return number;
        }

    }
}
