Finding gcd of array in c++

WebIt returns an iterator pointing to the first occurrence of the string strvalue in the array arr. Whereas, if the string value does not exist in the array then it will return an iterator pointing to the end of the array arr. Now after the function std::find() returns an iterator, we need check if the iterator is valid or not. It means we need to ...
