Abstract:
The key idea to arithmetic coding was done and implemented completely by replacing
the input symbol with a specific code. A series of symbols can be coded by the interval zero
to one, closed interval [0, 1]. Arithmetic coding using many methods and need many bits
especially if the message is long and complex, so the compression must be found to reduce
the number of bits by using probability methods. Also by combination between methods we
can reduce the interval [0, 1] to less than using one method for arithmetic coding
