The Data Day 8 is really more a puzzle than a coding challenge. We’re given the inputs and outputs from a broken 7-segment display (like on a digital clock).

The Data For Day 7 we move from fish to crabs, that are supposedly using submarines 🤷. I did not come up with the context for this! Either way, we are given a vector of (1-dimensional) positions for each crab and need to identify the position where all crabs can meet that involves the smallest amount of movement.

The Data For Day 6 we have to model the growth of a population of fish…this is much closer to my comfort zone. See the explanation for today’s challenge here.

The Data It’s Day 5 and we’re 20% of the way through the advent challenge! See the explanation for today’s challenge here. Today’s challenges will again involve working with indexing numbers in The Matrix a matrix.

The Data See the explanation for today’s challenge here. Most of the data we’ve dealt with so far has been 1 dimensional vectors, but for Day 4 we’re going to start working with 3-dimensional data.

The Data See the explanation for today’s challenge here. This time we need to work with binary numbers. We’re given a vector of numbers written in binary (e.g. 00100, 11110) and we need to use these to extract two values.

See my solution for Day 1 here. The Data See the explanation for today’s challenge here. For day 2, our data are a set of directions that we can use to explore the ocean floor that we mapped out on Day 1.

It’s that time of year again. Houses are lit up, presents are being bought, and Michael Bublé has emerged from his hibernation to create another album of Christmas songs. This year, in the spirit of giving, I will share my code for the 2021 Advent of Code challenges.

R 4.1.0 It’s been talked about for awhile, but the next big changes to R, v.4.1.0, are here! For many R users, new versions don’t make a huge amount of difference to their day to day work.

James Bond is a bit out of touch.
