/*이상한 문자 만들기
문제 설명
문자열 s는 한 개 이상의 단어로 구성되어 있습니다. 각 단어는 하나 이상의 공백문자로 구분되어 있습니다. 각 단어의 짝수번째 알파벳은 대문자로, 홀수번째 알파벳은 소문자로 바꾼 문자열을 리턴하는 함수, solution을 완성하세요.
제한 사항
문자열 전체의 짝/홀수 인덱스가 아니라, 단어(공백을 기준)별로 짝/홀수 인덱스를 판단해야합니다.
입출력 예
s return
try hello world TrY HeLlO WoRlD
입출력 예 설명
try hello world는 세 단어 try, hello, world로 구성되어 있습니다. 각 단어의 짝수번째 문자를 대문자로, 홀수번째 문자를 소문자로 바꾸면 TrY, HeLlO, WoRlD입니다. 따라서 TrY HeLlO WoRlD 를 리턴합니다.*/
