There are two categories of solutions. The hard way would comprise basically reversing the letters in the sentence and also reversing the letters in each word. That would correct the problem. This is not a good solution, but one the interviewer might expect. The better way is to use the standard library methods. In C++ you would define an iterator for the std::reverse function that understands what is meant by words. Now you've not only solved the problem given, but you have an iterator where you could use every standard library algorithm with the sentence.

I was hoping you would solve it without using trim or split helpers.
