Solutions written in C, Nim, Factor and... Zig
This is an incomplete set of solutions to 2020's Advent of Code. I started with C, and then used the problems as a starting point for playing with Nim, Factor and Zig. Thus most of these solutions are probably not very idiomatic.
Requires a C compiler and make. In the c/ subdirectory, edit the Makefile to your satisfaction, and then run make -r to build all available solutions. You can build a particular day by specifying a number make -r n.
Requires Nim. You can use nimble build from within the nim/ subdirectory to build the executables. If you have make installed you can also use the provided Makefile to build all solutions (make or make all) or just a particular day (make n).
Requires Zig 0.8.0. To compile the solutions, run zig build from within the zig/ sub-directory. This will create a zig-out/bin directory containing the executables which can be run as described below (or alternatively, run zig build n to execute the nth day's solution)..
Requires Factor. The easiest way to run the solutions is to copy the contents of the factor/ subdirectory into the work root of your Factor installation (see here for further information on vocabulary roots in Factor). The solutions can either be run by factor, or deployed as binary executables:
factor -run="1" # run day 1 solution
factor -e='USING: tools.deploy ; "1" deploy' # build day 1 solution as executableNote this creates the executables in your Factor installation.
Problem inputs are read from STDIN:
./n < input.txtThe solutions to both parts of the problem are then printed:
A) ... solution here ...
B) ... solution here ...
