Project Euler - Problem 14 Longest Collatz sequence, or "What I didn't learn from problem 8"
As my regular reader will doubtless remember, I recently blogged about the important lesson I learnt while solving problem 8 . I prophetically commented there...
"So, am I going to contemplate my problem domain before diving in and coding next time? Probably not, but at least if I don't, I might have some idea where to look when the bug reports come in!"
Hmm, I thought I was joking! Well, sadly I wasn't.
