BerOS file system

题意翻译

### 题目描述 新的操作系统BerOS有一个很好的特性。可以在路径中使用任意数量的字符“/”作为分隔符，而不是使用一个传统的“/”。例如，字符串`//usr///local//nginx/sbin//`和`/usr/local/nginx///sbin//`是等效的。只有根目录的路径可以表示为单个字符“/”，才需要路径末尾的字符“/”（或此类字符的某些序列）。 如果路径包含尽可能少的字符数“/”，则称为normalized的路径。 您的任务是将给定路径转换为规范化形式。 ### 输入格式 一行，仅包含小写字母和`/`的字符串，保证路径至少含有一个`/`，不超过 $100$ 个字符。 ### 输出格式 一行，一个字符串，表示简化后的路径。

题目描述

The new operating system BerOS has a nice feature. It is possible to use any number of characters '/' as a delimiter in path instead of one traditional '/'. For example, strings //usr///local//nginx/sbin// and /usr/local/nginx///sbin are equivalent. The character '/' (or some sequence of such characters) at the end of the path is required only in case of the path to the root directory, which can be represented as single character '/'. A path called normalized if it contains the smallest possible number of characters '/'. Your task is to transform a given path to the normalized form.
