Completely agree with you, prbsh9, I thought the same thing. Spent a bit of time answering the question that was posed, only to find out it was a waste of time because the solution requires a completely different approach. Apparently, we're supposed to be mind readers. I'm glad I answered the actual question that was asked correctly; just a shame I have to press 'skip' now.

Lol I feel you on that. I def need to work more on my algorithms.

This should be a test case Test.assertEquals(incrementString("9"), "10");
