Challenge 1: begin/rescue/ensure — Solution

def safe_divide(a, b)
  begin
    a / b.to_f
  rescue ZeroDivisionError
    nil
  ensure
    puts "Division attempted"
  end
end

puts safe_divide(10, 2).inspect
puts safe_divide(10, 0).inspect

=begin
Output:
Division attempted
5.0
Division attempted
nil

Notes:
- b.to_f forces float division (Chapter 2 of Course 1's integer-division
  gotcha) so safe_divide(10, 2) returns 5.0 rather than truncating.
- rescue ZeroDivisionError catches only that specific error type — any
  other kind of exception would not be caught here and would propagate up
  normally.
- ensure runs after both the successful call (10, 2) and the rescued call
  (10, 0) — "Division attempted" prints in both cases, before the return
  value is even displayed by puts.
