✏️ 문제 설명
모든 판매원은 자신이 칫솔 판매에서 발생한 이익 뿐만 아니라, 자신이 조직에 추천하여 가입시킨 판매원에게서 발생하는 이익의 10% 까지 자신에 이익이 됨
판매원과 각 판매원을 다단계 조직에 참여시킨 다른 판매원이름이 주어지고,
판매량 집계 데이터의 판매원 이름과 판매량 집계 데이터의 판매 수량이 주어질 때,
각 판매원이 득한 이익금 배열 구하기
🔍 풀이 방법
dfs, HashMap 이용
dfs를 돌리면서 각 판매원이 자신을 참여시킨 상위 판매원에서 얼마를 줘야하는지 재귀 돌리면서 쭈우우욱 계산
⏳ 회고
문제가 오지게 길어서 어려울 줄 알았는데, 생각보다는 괜춘
