An example of using Benchmark lib in Ruby

benchmark_example.rb

require 'benchmark'

# Compare sorting a Hash with an Array
arr = []
hash = {}

10_000.times.with_index do |i|
  ascii_code = rand(255)
  random_char = ascii_code.chr
  arr << random_char
  hash[i] = random_char
end

# puts arr.inspect
#puts hash.inspect
#sh=[]

Benchmark.bm(7) do |x|
  x.report 'Sort Array' do
    arr.sort!
  end
  
  x.report 'Sort Hash' do
    sh = hash.sort_by{|_key, value| value}
  end
end

# puts arr.inspect
# puts sh.inspect
# puts hash.inspect
