Advent of Code Template TS

This is a template for Advent of Code, written in TypeScript.

How to use

For each day, navigate to the respective folder in src.

• Place your input for each day in input.txt.
• Place your code in index.ts, between lines 10 and 12.

There are 4 different functions that parse your input:

• readInputRaw - reads the input raw, does not modify it
• readInputSplit - reads the input and splits it by line
• readInputSplitNum - reads the input and splits it by line, then converts every line to a number
• readInputGrid - reads the input and splits it by line, then splits each one by character to make a 2D grid

If you want to display a grid, there are 2 different functions. Each takes in a grid (a 2D array) and an optional replacer. Both function identically without the replacer, but the implementations of the replacer are different.

• displayGridObjConfig - takes a key/value pair and maps each value in the grid that matches the key to the value
• displayGridFuncConfig - takes a function that maps a grid value to a string, and executes it on each value (if the function returns nothing for a particular value, it is unmodified)

There are scripts to run each day with ts-node. Each script name is "day" followed by the number. For example, Day 18's puzzle executed via npm would look like npm run day18.
