Today’s Riddler has a problem - you have a music player with 100 songs, and can only seek a song with “next” and “random”. “random” chooses a number uniformly in 1:100, next is track + 1, and 100 wraps back around to 1. You’ve started on a random track, and want to get to track 42, with as few presses as possible.
In my short time in UCU we entered a pay dispute that lead to a series of strike actions. The dispute boiled down to “inflation is eroding our wages, at least pay us as much in real terms as we were worth a few years ago”.
I recognised today’s Riddler problem and recognised that it’s reasonably easy to attack by Monte Carlo testing rather than my (weak) probability/combinatorics.
