### 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;
void input(char s[]) { cin.getline(s, 1001); }
void remove(char s[]) {
  int n = strlen(s);
  for (int i = 0; i <= strlen(s); i++) {
    if (s[i] == '/' && s[i + 1] == '/') {
      for (int j = i; j < strlen(s); j++) {
        s[j] = s[j + 1];
      }
      i--;
      n--;
    }
  }
  s[n] = '\0';
  while (s[n - 1] == '/' && (strlen(s) > 1)) {
    s[n - 1] = '\0';
  }
  cout << s << endl;
}
int main() {
  char s[1000];
  input(s);
  remove(s);
  return 0;
}

```
