이 문제는 단어 한 개를 입력받고 스펠링을 하나 하나 나누어 출력하는 문제였다. 처음에 바로 널문자가 나오기 전까지 반복문을 돌려서 하나하나 출력하면 되겠구나!! 라고 생각을 했는데 무슨 이유에서인지는 모르겠는데 char에 for문을 돌리고 null문자가 나오면 break해라 라는 반복문을 돌렸더니 에러가 떴다....! ㅎㅎ 지금 다시 해보았더니 (사실 어제 너무~~~ 졸려서 이거 오류가 왜 뜨는지까지 찾을 힘이...ㅎㅎ) import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.IOException; import java.io.InputStreamReader; import java.io.OutputStreamWriter; ..
