Hello Grant. It's a nice set, but for problems 3001 and 3002 lookup tables are "always win" solutions. For this problem you can avoid this by using some randomness in the test suite.
I'm glad you like them, and thanks for the feedback. I just added a random test case to all three problems.
Yeah, the series is good. After a few rounds of spam-storm, Cody seems to be back on track...
