Usage

require "algoruby"

Examples:

Algoruby::GroupAnagrams.call(["bebop", "bobep", "pebop", "epbop", "opbeb", "peobe"])
#=> [["bebop", "bobep", "opbeb"], ["pebop", "epbop"], ["peobe"]]

Algoruby::BinarySearch.call(["Trane", "Bird", "Dizz", "Bud", "Monk" ], "Dizz")
#=> 2

Algoruby::SlidingWindow.each_window([1, 2, 3, 4, 5], 3)
#=> [[1, 2, 3], [2, 3, 4], [3, 4, 5]]

Algoruby::SlidingWindow.aggregate([1, 2, 3, 4, 5], 3) { |w| w.sum }
#=> [6, 9, 12]
