Resolved: Categorizing a number based on ranges

very_low = <10
low = 11-20
medium = 21-30
high = 31-40
very_high = 41+
[/code]

</p>



What is the most succinct way in Ruby to find out which category any given number is in?<br> 



e.g know that 23 would be 'medium'<br> 



<h2>Answer:</h2>



I would do:<br> 


<p>[code]RANGES = {<br />
  very_low:    (..10),<br />
  low:       (11..20),<br />
  medium:    (21..30),<br />
  high:      (31..40),<br />
  very_high: (41..)<br />
}</p>
<p>def range_for(number)<br />
  RANGES.find { |_, range| range.cover?(number) }.first<br />
end</p>
<p>range_for(23)<br />
#=> :medium
