state s and you want to encode the the symbol a in this case in this very particular case what a in this will do is produce the number 2's 2 times X so remember the state s is a natural number and if you wish to encode B it produces the this state 2's plus 1 so that this is ans for for this very simple source um of course the ans will generalize more but just for in this case this is all it does and so you can see that really what this is doing is its appending numbers zeros and ones on the right of a binary representation of the
