I’m always on the look out for fun exercises to practice programming. I’ve already covered some of the problems in the Project Euler project (they get hard very quickly). Another great initiative I found was Rosalind.
Rosalind offers an array of intellectually stimulating problems that grow in biological and computational complexity; each problem is checked automatically, so that the only resource required to learn bioinformatics is an internet connection.
I’ve solved a few problems so far, just getting my feet wet. I’ll eventually get around to sharing them here.
