this is how I resolved it. Just following the instruction

a_to_m = crew.select(&first_half)

first_half = lambda { |x,y| y < “M”}

puts a_to_m

I hope it can be helpful

I tried your code in replit.com, @marcopalumbo35989018 , but the order of the first two lines stopped it running properly. Switching their places worked fine.

Hi everyone!

With a lot of these exercises I manage to pass them, but I struggle to put into plain terms what the code is doing.

Am I correct in saying something like this for line 13: Filter the crew hash using the first_half lambda and store those values in the a_to_m variable?


In case breaking it down further helps:

Calling the select method on the crew hash.

Passing the first_half lambda as a block to filter out names < 'M'.

Storing the filtered results in the a_to_m variable as an array.
