[실패/풀이참고] 레벨1. 기능개발 - 큐/스택
de36ee3 
#3 #9

- 경험이 부족해서, 큐, 스택을 어떻게 활용해야할 지 몰라서 Map이랑 섞어쓰다가 시간초과로 포기하고 답을 참고했다.

[풀이참고] 레벨2. 가장 큰 수 / 문자열 정렬

#3 #9

[풀이참고] 레벨2. 전화번호 목록 - 해시 | 연습필요
64555d8 
#3 #9

- 해시에 전화번호를 다 담아두고
- 접두사를 찾는거니까, 단어의 글자 길이로 반복문으로 순회해서 해시에 있는 문자 탐색

- 뭔가 contains 관련 문제는 해시를 쓰는게 좋은듯?

#3 #9
