Question

I have four sizes, each are in a hash by their square feet:

# The sizes. Sizes are in sq ft (min, max)
size_hash = {
  'Large'  => [70,139],
  'Medium' => [15,69],
  'Small'  => [1,14]
}

If I’m given the number 40, how can I return Medium as the size from the array?

Do I need to do something like this?:

# The sizes. Sizes are in sq ft (min, max)
size_hash = {
  [70..139]  => 'Large',
  #... etc
}

Answer 1

You could use a proc:

size_store = proc{ |n|
  case n
  when 70..139
    'Large'
  when 15..69
    'Medium'
  when 1..14
    'Small'
  end
}
# USAGE: size_store[40]
