Dear all,

Can you help me how can I implement my own "has_key" method for "hash class."

class Hash

	def my_each_key(&block)
		self.each { |key|
		yield(key[0])
		}
	end
	
	def my_each_value(&block)
		self.each { |value|
		yield(value[1])
		}
	end

	def has_key()
		#todo
	end

end

h = {1 => 1.0, 2 => 2.0, 3 => 3.0 }

many thanks in advance,

salai.
