(복수 문자간의 이동)
핵심원리
1. start type(임의의 시작문자)과 final type(최종적으로 보여주고자 하는 문자열)을 지정한다. ( 우리는 "-"와 "superman"로 합니다.)
2. superman의 각 문자를 배열을 이용하여 저장한다.
3."--------" =>"superman" (목적-->종착 ) 두 문자를 유니코드로 변경한다.
3. 각 문자에 순차적으로 deley를 주어 단계적으로 변환하도록 한다.
(0번째 배열의 이동시작 x초 후 1번째 배열 이동시작 ) 즉 ("-"=>"s", "-"=>"u","-"=>"p" 의 이동이 x초 간격으로 일어난다.)
4. 유니코드를 다시 문자열로 변화해서 화면에 표시
** 하단의 debugging 결과를 보면 순차적으로 코드이동이 있음을 확인 할 수 있다.
