Suppose we have an optimal prefix code on a set c={0,-1} of characters and we wish to transmit this code using as few bits as possible. show how to represent any optimal prefix code on c using only 2n -1 + n[lgn]. (hint: use 2n -1 bits to specify the structure of the tree, as discovered by a walk of the tree.)

plot immersion i am not fully sure with it though
