A group of computer scientists wants to create a fixed-length compression algorithm. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each symbol of the alphabet. As part of this group of computer scientists, your goal is to write a program to determine the alphabet used by the message to be compressed (set of different characters in the input message), and the frequency of each symbol in the alphabet, using conditionals, loops, and arrays.
