using namespace std;
string s,digit,seq,temp;
int main()
{
    cin>>s;
    for(int i=0; i<s.length(); i++)

            s[i] = ' ';
    bool flag = false;
    s+=" ";
    //init
    temp = digit = seq = "";
   for(int i=0; i<s.length(); i++)

       if(s[i] == ' ')
       {
          if(flag || (temp[0] == '0' && temp.length()>1) || temp.length() == 0)
          {
