 int countSegments(string s) {
         if( s.size() == ){
             return ;
         }

         vector<string> v;
         for( int i = ; i < s.size(); i++){
             if( isspace(s[i]) ){
                 continue;
             }
             int j = i+;
             while( !isspace(s[j]) ){
                 if( j < s.size() )
                     j++;
                 else
                     break;
                 }
             string sb = s.substr(i,j-i);
             v.push_back(sb);
             if( j == s.size() )
                 break;
             i = j;
         }

         int n = v.size() ;
         return n;
     }
