Last week I gave the geeks at #neverfear IRC a coding task, something I've been trying lately to both challenge them and myself. The challenge I gave them was actually a real-life problem I'd faced in industry as a developer. The challenge was as follows.
Produce an algorithm in the language of your choice that recursively converts a numerical value to a hexidecimal string without bitwise operators. Bonus points awarded for generalising your algorithm to the nth base.
We had a few good solutions mostly following a similiar approach in various languages that I'd like to share.
