All solutions expect the input via stdin, which can be easily achieved by piping the input to the program: julia 1.jl < input.in. I use the program-tester.sh script (see here), which runs the given program on all *.in files in the directory, and tests whether the corresponding *.ans file matches the given output. Each program outputs both part 1 and part 2 on separate lines. To validate a program manually, type diff <(julia 1.jl < input.in) input.ans.
Programs are initialized with the init-day.sh script. I.e. typing init-day.sh 10 initializes the 10th day by creating a folder named 10, downloading the input test case with the session.cookie, copying the dummy.py file and opening the solution file.
- 2021: There is a solution for each problem in Julia. Sometimes there is a Python or APL solution as well. I'm trying out Julia for the first time, mostly focusing on short and elegant code.
