Newcomers to programming would benefit from practicing drills regularly until basic problem solving becomes second nature. This gem is a command line tool that allows users to solve randomly generated small problems.
It currently supports drills surrounding simple and complex data structures.
$ gem install rubies
rubies
After typing rubies into your terminal, you will see the Splash screen:
After starting, you will see randomly generated data structures for you to work through:
Here, you are being asked to find 865 in the array called current, which is located in the 3rd position (or index of 2). The answer would be the following:
[1] rubies(main)> current[2]
=> 865
Here, you are given a hash called current and are being asked to find the right command for engineer collaborative schemas. The key associated with that value is Bergnaum-Pouros, so the answer would be the following:
[1] rubies(main)> current["Bergnaum-Pouros"]
=> enable collaborative schemas
Here, you are given an array with a hash in it, or a compound data structure, and are being asked to find (106) 777-4274. This is how you could go about it:
[1] rubies(main)> current[0]["Mikel Herman"]["phone"]
=> (106) 777-4274
Type new to get another data structure or exit to quit and see your final score. Try to do 15-20 minutes every day and you will be in great shape!
