Hello, I'm trying to pass a block when I call the function but it's returning an error. Can you please help me?
class SimpleBenchmarker
def run(description, &block)
start_time = Time.now
block.call
end_time = Time.now
elapsed = end_time - start_time
puts "\n#{description} results"
puts "Elapsed time: #{elapsed} seconds"
end
end
benchmarker = SimpleBenchmarker.new
benchmarker.run("Your", do puts "Hello world!" end)

class SimpleBenchmarker
def run(description, &block)
start_time = Time.now
block.call
end_time = Time.now
elapsed = end_time - start_time
puts "\n#{description} results"
puts "Elapsed time: #{elapsed} seconds"
end
end
benchmarker = SimpleBenchmarker.new
benchmarker.run "Your" do puts "Hello world!" end
