Consider the following data compression technique. We have a table of m text strings, each at most k in length. We want to encode a data string D of length n using as few text strings as possible. For example, if our table contains (a,ba,abab,b) and the data string is bababbaababa, the best way to encode it is (b,abab,ba,abab,a)- a total of five code words. Give an O(nmk) algorithm to find the length of the best encoding. You may assume that every string has at least one encoding in terms of the table.
