### Prompt

Develop a solution in CPP to the problem described below:

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.

Input

The first line of the input contains only lowercase Latin letters and character '/' — the path to some directory. All paths start with at least one character '/'. The length of the given line is no more than 100 characters, it is not empty.

Output

The path in normalized form.

Examples

Input

//usr///local//nginx/sbin


Output

/usr/local/nginx/sbin

### Response

```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
  string path;
  cin >> path;
  ;
  string new_path;
  bool added_slash = false;
  for (unsigned int i = 0; i < path.length(); i++) {
    if (path[i] != '/') {
      added_slash = false;
      new_path += path[i];
    } else {
      if (!added_slash) {
        new_path += '/';
        added_slash = true;
      }
    }
  }
  if (new_path[new_path.length() - 1] == '/' && new_path.length() > 1)
    new_path = new_path.substr(0, new_path.length() - 1);
  cout << new_path;
  return 0;
}

```
