100 algorithms challenge in Ruby

I found it interesting to apply the initial challenge of 100 days of algorithms from coells that was originally done with Python using Jupyter, in Ruby language.

I don’t copy the algorithm from the repository. I solved them myself (and more importantly I understand them) or do some researches to solve them :). Sometimes solutions are similar, sometimes not.

The objective is to use the original repository as a list of algorithms to cover. Try to understand what each algorithm does, and solve it.
