Question 4

Essay

For the LZW algorithm, assume an alphabet {\{* a b o d }\} of size 5 from which text characters are picked.
Suppose the following string of characters is to be transmitted (or stored):
dabbadabbadabbadoodoo\mathrm{dabba} * \mathrm{dabba} * \mathrm{dabba} * \mathrm{doo} * \mathrm{doo} \ldots
The coder starts with an initial dictionary consisting of the above 5 characters and an index assignment, as in the following table:
