Posted 2021-05-16

require 'benchmark'

a = ('a'..'zzzzz').to_a
h = {}
a.each {|e| h[e] = :ok}

Benchmark.bmbm do |x|
  x.report("find z in array") { a.include? 'z' }
  x.report("find zz in array") { a.include? 'zz' }
  x.report("find zzz in array") { a.include? 'zzz' }
  x.report("find zzzz in array") { a.include? 'zzzz' }
  x.report("find zzzzz in array") { a.include? 'zzzzz' }
  x.report("find z in hash") { h.include? 'z' }
  x.report("find zz in hash") { h.include? 'zz' }
  x.report("find zzz in hash") { h.include? 'zzz' }
  x.report("find zzzz in hash") { h.include? 'zzzz' }
  x.report("find zzzzz in hash") { h.include? 'zzzzz' }
end
