### Prompt

Construct a CPP code solution to the problem outlined:

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

}
using namespace std;
int main() {
  string s, ans;
  cin >> s;
  for (int i = 0; i < int(int((s).size())); i++) {
    if (s[i] != '/')
      ans.push_back(s[i]);
    else {
      int idx = i;
      while (idx < int((s).size()) && s[idx] == '/') idx++;
      ans.push_back('/');
      i = idx - 1;
    }
  }
  while (!ans.empty() && ans[int((ans).size()) - 1] == '/')
    ans.erase(int((ans).size()) - 1);
