A collection of solutions to selected challenges from the r/dailyprogrammer subreddit. A link to a thread with detailed description of the challenge can be found in the source code of each solution. Some problems, most notably evolutionary programming (#249) and Markov chain text generation (#270) have inspired larger projects, some of which can be found in their own repos. Note: the pi calculator from images of circles works only with Python 2, as the PyPNG library is not available for Python 3 yet.
