I've forgotten most of the algorithm stuff I learned at university that I haven't used in my job. I know how dynamic programming works and I can recognise such a problem, but don't ask me to implement it in an hour. I know how graphs work and what the various algorithms are, but why would I implement any of them when I can just import networkx?
