### Prompt

Your task is to create a Cpp solution to the following problem:

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>
const int INF = (int)1e9;
const int long minINF = (int)-1e9;
const int mod = (int)1e9 + 7;
const int MAXN = (int)1e5 + 5;
using namespace std;
string s;
string n;
int main() {
  ios_base::sync_with_stdio(false);
  cin.tie(nullptr);
  cout.tie(nullptr);
  cin >> s;
  int sent = 0;
  int i;
  for (i = 0; (s.c_str())[i] != '\0'; i++) {
    if ((s.c_str())[i] != '/') {
      sent = 1;
      break;
    }
  }
  if (!sent) {
    cout << "/";
    return 0;
  }
  sent = 0;
  for (i = 0; (s.c_str())[i] != '\0'; i++) {
    while (sent == 1 && (s.c_str())[i] == '/') {
      i++;
    }
    if (sent) {
      sent = 0;
      i--;
      continue;
    }
    if (s.c_str()[i] == '/') {
      sent = 1;
    }
    n.push_back(s.c_str()[i]);
  }
  if (n.back() == '/') n.pop_back();
