The last 2 draws, Saturday and Monday, I managed to match exactly one white ball in the double draw... nothing on the main game.

On the 24th attempted challenge at rosalind.info I submitted an answer that did not pass. That was the first fail, and there was much to learn from it. Last night I took another read of the problem and finally figured out what they were expecting, a recursive depth first search of the space provided... then I passed it! I have not dealt with recursion or DFS since my data structures and algorithms classes. Another win for choosing to learn bioinformatics/biostatistics is getting the chance to apply literally everything I had learned in school but did not use since.
