I didn't get this what they had done. If somebody knows please explain.The code by hackerrank is pasted below:
using namespace std;
string ltrim(const string &); string rtrim(const string &);
int main() { string n_temp; getline(cin, n_temp);
int n = stoi(ltrim(rtrim(n_temp))); // Write your code here return 0;
}
string ltrim(const string &str) { string s(str);
s.erase( s.begin(), find_if(s.begin(), s.end(), not1(ptr_fun<int, int>(isspace))) ); return s;
string rtrim(const string &str) { string s(str);
s.erase( find_if(s.rbegin(), s.rend(), not1(ptr_fun<int, int>(isspace))).base(), s.end() ); return s;
