public static class Kata
{
  public static string RemoveUrlAnchor(string url)
  {
    foreach(char c in  url){
      if(!url.Contains('#')){
        return url; 
      }
    }
    string output="";
    for(int i=0;i<url.Length;i++){
      if(url[i]=='#'){
        output=url.Remove(i,url.Length-i);
        }
    }
    return output;
  }
