### 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>
using namespace std;
const long long int M = 1e18 + 7;
const long long int mod = 1e9 + 7;
const long long int infi = LLONG_MAX;
long long int ans, k, n, x, y, m, mymax = LLONG_MIN, mymin = LLONG_MAX, b, c, z,
                                  sum;
int main() {
  string s;
  cin >> s;
  n = s.size();
  long long int i = 0;
  vector<string> fans;
  while (i < n) {
    if (s[i] != '/') {
      string temp;
      while (s[i] != '/' && i < n) {
        temp.push_back(s[i]);
        i++;
      }
      fans.push_back(temp);
    } else
      i++;
  }
  if (fans.size() == 0) {
    cout << "/";
  } else {
    for (auto kk : fans) {
      cout << '/' << kk;
    }
  }
  return 0;
}
