프로그래밍/HackerRank
요즘 틈틈이 알고리즘 기초 공부를 하고 있는데, HackerRank 문제를 풀면서 나의 풀이를 기록으로 남겨보려 한다.
Problem :
https://www.hackerrank.com/challenges/reduced-string/problem
My Solution :
#!/usr/bin/env python3 def super_reduced_string(s, i): if i < 0: i = 0 while i < len(s) - 1: if s[i] == s[i+1]: return super_reduced_string(s[:i] + s[i+2:], i-1) i += 1 return s s = input().strip() result = super_reduced_string(s, 0) print(result) if result != '' else print('Empty String')
My Solution2 :
#!/usr/bin/env python3 def super_reduced_string(s): res = [] for c in s: if res and c == res[-1]: res.pop() else: res.append(c) return ''.join(res) s = input().strip() result = super_reduced_string(s) print(result) if result != '' else print('Empty String')
