What is Code Golf?

Based on the original perl golf, Code Golf allows you to show off your code-fu by trying to solve coding problems using the least number of keystrokes.

You're not just limited to Perl either - PHP, Python and Ruby are all available too.

Challenges are always open, and your entries are automatically scored so you can start playing right away!

Tower of Hanoi

Posted 13.04.2007 by carldr.

To celebrate the first Friday the 13th of 2007, we have a new challenge for you kerrrazy golfers. I’m sure most of you have heard of the Tower of Hanoi. This challenge requires you to take a starting position of the puzzle and organise the pegs onto one peg. Read all about it on the Tower of Hanoi challenge page, where you’ll see all the information you need.

I’m going to make the bold promise that we’ll have a new challenge next Friday, but I’ve said that before so we’ll see if it actually happens!

Musical Score

Posted 08.03.2007 by carldr.

It’s been more than a month since the last challenge, many apologies for the delay in posting a new challenge. So let’s hope you like it!

Musical Score asks you to parse a music score and output the notes which are represented on it. In my opinion, it’s quite an interesting problem. As usual, visit the challenge’s page to see the full details.

We’re hoping it won’t be anywhere near as long until the next challenge, and there have been a few interesting challenges posted on the forums. If you have any suggestions, you can post them there, or email me them at the address at the bottom of each Code Golf page.

Scheduled Downtime

Posted 12.02.2007 by carldr.

A quick note to let you all know that there will be roughly 30 minutes downtime from about 16:30 GMT tomorrow (Tuesday) afternoon for some essential server upgrades. During that period the Code Golf server will be completely unavailable.

Roman to Decimal

Posted 04.02.2007 by carldr.

A new challenge has arrived in the shape of ‘Roman to Decimal’. The problem is exactly as it sounds – Your code will be given some Roman numerals, and it will have to convert them to the system we’re all more familiar with.

There are 25 test cases, so hopefully there won’t be any luck-based submissions for this challenge!

Thanks must go to Flagitious for putting this challenge together, as well as writing the description. Good work man!
