This is my first time with the Advent of Code challenge. This is my code for for the puzzles written in Rust.
I'm a beginner and using this challenge to learn the language!
- launches from the command line and takes arguments for the day and an input file. Calculates the two results.
- Proof of concept really. The challenge was relatively easy and input was one value per line..
- Built more data structures.
- First challenge with more complex data input with different data separators.
- For data input, used the
filter_map()method to deal with the different characters and convert to Rust vectors (similar to arrays in other languages). - Used the
gridcrate to create a 2D addressable vector structure to map the sea vents. I intended to not use much beyond the standard library. This was a compromise to just get sane 2D addressing without writing it myself. - Challenge1: Used loops to put each integer on the grid. othing special.
- Challenge2: Same as Challenge 1 but with the addition of test logic to subtract index numbers for addressing since Rust can't iterate backwards without re-typing and additional methods.
- Challenge 1: Used a growing vector in the same format as the input data. This was suitable for the small number of growth cycles in the puzzle.
- Challenge 1: assigned values and spawned new fish with a match operation.
- Challenge 2: Used the standard library
collections::DeqVecfor to be able to roll the vector end to end.
- This challenge was more of a problem solving and math exercise rather than an intense programming challenge.
- Challenge 1: Solved by find the median.
- Challenge 2: Found the basic formula that describes the fuel rate. Loop from the lowest to highest possible values to find the one that has the minimum total fuel use.
- Used a closure in Challenge 2 to hold the fuel burn formula.
- The first challenge is a teaser where you just have to count how often specific patterns appear.
- Challenge 1: Text processing and splitting followed by matches on character counts.
To be completed.
