Python Challenge
Found out about The Python Challenge. While you don't need to use Python to solve most of the problems, a knowledge of the language certainly helps. While the initial problems are fairly easy, some of the later ones are quite difficult, and cover many topics. If you decide to have a go, here are a few hints that might help: Keep a log of what you do. Solutions to may provide insight into subsequent problems. Look at ALL the information provided to you. If the solution isn't apparent, look for patterns in the information and extrapolate. If you are using brute force to solve a problem, there is probably a quicker and simpler method to get the answer. If you get stuck, check the forum for hints. There is also a solutions wiki, however, you need to have solved the corresponding problem before it will give you access.
