be expressed as 2 to the power L I then you can encode using the same scheme that symbol X I with a length L I bitstream into a tree that would be built up the way the tree was built up over here haven't threw in this but that's kind of the rough intuition and we'll see is of course things that generalize this to simple we're P of X is not necessarily one over two to the power of something that could be any probability different from a power of 1/2 okay so that's some high-level intuition let's now take a look at some of the theory that we can
