Sorting a Hash
The sort_by method allows you to sort a hash according to keys or values. Below is the Ruby program to sort a hash:
hash = { "b" => 2, "a" => 1, "c" => 3 }
sorted_by_key = hash.sort_by { |key, value| key }
sorted_by_value = hash.sort_by { |key, value| value }
puts sorted_by_key.to_h # Output: {"a"=>1, "b"=>2, "c"=>3}
puts sorted_by_value.to_h # Output: {"a"=>1, "b"=>2, "c"=>3}
Output
{"a"=>1, "b"=>2, "c"=>3} {"a"=>1, "b"=>2, "c"=>3}
