When running tasks you have to pass filename from command line like this:

a) Ruby

# inside day-X directory, where X is day number
ruby ruby/solution.rb input.txt

# inside day-X/ruby directory
ruby solution.rb ../input.txt

b) C++

# inside day-X directory, where X is day number
g++ cpp/main.cpp -o cpp/output && ./cpp/output input.txt

# inside day-X/cpp directory
g++ main.cpp -o output && ./output ../input.txt
