Given an optimal prefix-free code on a set C of n

Given an optimal prefix-free code on a set C of n characters, you wish to transmit the code itself using as few bits as possible. Show how to represent any optimal prefix-free code on C using only 2n1+nlgn bits. (Hint: Use 2n1 bits to specify the structure of the tree, as discovered by a walk of the tree.)
