思路:
- 模拟栈操作,遇到目录名入栈,遇到
..就出栈,那么,最后还在栈里面的,就是剩下的完整目录应有的各个目录名 - 
代码:
class Solution:def simplifyPath(self, path: str) -> str:# 去掉重复的斜杠items = [item for item in path.split(*'/') if item != '']stack = []for item in items:if item == '.':continueelif item == '..':if not stack:continueelse:stack.pop()else:stack.append(item)return '/'+'/'.join(stack)
