Get all keys in hash with same value

Question

I am trying to get all the keys with the same value from a hash and put them into an array as separate entries. I have this line of code but it sends everything in as a sing

Answer 1

Or even better, yet simpler:

h.select { |k,v| v == h.values.max }.keys

For example,

h = { "a" => 1, "b" => 2, "c" => 2 }
# implement the above solution
h.select { |k,v| v == h.values.max }.keys
    #=> ["b", "c"]

Hopefully, that's what you'd want! :)
