List four programming functions that can be carried out using the program organizer.
Suppose that n ≥ 2, A = {a1,...,an} = B, and the channel respects a1,..., an-1 perfectly. Suppose that, when an is sent, the output characters a1,..., an are equally likely to be received. Find the optimal input frequencies and the capacity of thi..
For this assignment, you will write a C program that uses its first command line parameter to compute and display a histogram of characters that occur in it.
