Introduction
본 문제에서는 입력 받은 문자열의 단어 단위 역순 변환 및 비교 기능을 수행하는 프로그램을 작성한다.
1. 문자열 변환 프로그램
Requirements
1.문자열 역순 변환 - 문자열을 입력 받은 후, 단어 단위로 역순 변환하여 출력한다. 단, 문자열에 숫자가 포함되어 있는 경우, 숫자는 역순 변환에 포함시키지 않는다. Ex. Thanks 2You  sknahT 2uoY - 단어는 공백 문자(‘ ‘) 를 기준으로 구분한다. - 입력 값에는 오류가 없다고 가정한다.
2.문자열 비교 - 두 개의 문자열을 입력 받은 후, 숫자를 제외하고 같은 문자열인지 확인하여 결과를 출력한다. 단, 대소문자는 구분하지 않는다. - 입력 값에는 오류가 없다고 가정한다.
3.다음 제약 사항을 준수한다. - 제시되지 않은 기능(ex. 오류메시지 처리, 프로그램 종료)은 Sample Run을 참조한다. - 조건이나 Sample Run에 명시되지 않은 예외상황은 고려하지 않는다. - 제공된 코드의 함수원형을 반드시 준수한다.
