Write a function that sorts the keys in a hash by the length of the ke

1.	Write a function that sorts the keys in a hash by the length of the key as a string. For instance, the hasht :
Answer» HSH.keys.map(&AMP;:to_s).sort_by(&:LENGTH) or: hsh.keys.collect(&:to_s).sort_by { \|key\| key.length } or : DEF key_sort hsh hsh.keys.collect(&:to_s).SORT { \|a, b\| a.length <=> b.length } end

Write a function that sorts the keys in a hash by the length of the key as a string. For instance, the hasht :

Answer» HSH.keys.map(&AMP;:to_s).sort_by(&:LENGTH)

or:

hsh.keys.collect(&:to_s).sort_by { |key| key.length }

or :

DEF key_sort hsh hsh.keys.collect(&:to_s).SORT { |a, b| a.length <=> b.length } end
