ruby - How to get the size of each value of a hash -

I have hashes, each value is an array.

I have a new array of each value / size of the array.

Example:

hash

  {"A" => ["1", "2", "3"], "b" = & gt; ["B", "break"]}

results

  [3, 2]

help you Thanks for

  some_hash Values.map {| V | | V.size}

and 1.9, I believe you can do this:

  some_hash.values.map (and size: )
