To run the code for a lesson, go to corresponding directory. Make sure the script build.sh is executable and then execute the following commands from your terminal
$ shards install --ignore-crystal-version
$ ./build.sh
$ ./a.out
The build.sh script will compile and link a lesson and produces the executable a.out
