새로운 프로젝트 드디어 마지막 easy 단계 프로젝트이다 ! Bulls and Cows는 우리나라로 치면 스무고개 같은 게임이다. 정답을 맞출때 까지 계속 대답하는 방식인거 같다. 만약 정답은 4931인데 정답을 1234라고 했으면 1 bull and 2 cows 라고 한다. 1 bull : 자리수도 맞고, 숫자도 맞음 2 cows : 자리수는 틀리지만, 숫자가 맞음 4 bulls 가 나오면 게임끝 이번 스테이지는 그냥 단순 출력만 하면 된다. public class Stage1 { /** * Turn 1. Answer: * 1234 * Grade: None. * * Turn 2. Answer: * 9876 * Grade: 4 bulls. * Congrats! The secret code is 9876...

이번 프로젝트는 오목게임 만들기 프로젝트 인것 같다. 외국에서는 Tic Tac Toe 로 불리는가 보다. 일단 1단계에서는 프린트만 하는 것 같다. public class Stage1 { public static void main(String[] args) { // write your code here String a = "O"; String b = "X"; System.out.println(b+" "+a+" "+b); System.out.println(a+" "+b+" "+a); System.out.println(b+" "+b+" "+a); } }
