Quixey Challenge: $100 for a 1-Minute Coding Puzzle

October 3rd, 2011 | Posted by Quixey in Technology

We hire engineers who think in algorithms, dream in code, and eat control structures for breakfast (e.g. Froot Loops). We’re looking for people with a sixth sense for good code – people who can fix bugs with their mind. So today, we’re introducing the Quixey Challenge.

The Quixey Challenge
We show you a famous algorithm with a bug, you fix it in 1 minute or less.

The Prize

If you successfully complete the challenge, we’ll send you

  1. $100
  2. An exclusive “founder’s edition” Quixey T-shirt

Not bad for 1 minute!

Ground Rules

  1. The algorithm will be implemented as a Python function.
  2. The function will not have a syntax error.
  3. The function won’t always return the correct thing.
  4. It will be possible to make the function return the correct thing either by adding one line of code, or by modifying one line of code.
