Ruby encode and decode method

string_encode_decode_method.rb

# created a method name 'encode' that accept an argument 'string'
# and then call the "pack('m')" method on the string
def encode string
	[string].pack("m")
end

# assign encode value of 'I love food' to string_encode variable.
puts string_encode = encode("I love food") # the return value is 'SSBsb3ZlIGZvb2Q='

# encoding strings is pretty cool, but how do you decode them?
# the method below decode strings perfectly.
# instead of pack, we use unpacked this time. This will give us the original string.
def decode string
	string.unpack("m")
end


# output the return value of string_encode when we pass it to the decode method
puts decode(string_encode)
