# I want to write a method that returns the first number in a sub array where the letter matches a passed in letter
# If passed in letter does not exist, it should return nil
a = [["a", 1], ["b", 2]]
# Implementation
def get_number_for_letter(arr, letter)
  arr.detect(Proc.new { [] }) { |d| d.first == letter }[1]
end
 
# Error received for case where letter does not exist
# This might just be me not understanding how detect is supposed to work
