Given two strings a1a2an and b1b2bm, find their minimum edit distance. The edit distance is the number of mismatches in an alignment. For example, the minimum edit distance between the two strings "SUNNY" and "SNOWY" in the following alignment is 3: Likewise, the minimum edit distance between "INTENTION" and "EXECUTION" is 5. (a) Represent the minimum edit distance between a1a2ak and b1b2bl by a function name. (f) Actually, we do not do any choice in dynamic programming. What we must do is first to consider all possibilities like above and choose the minimum of those right-hand sides. Now you are ready to minimize them. Write down the whole formulation which collects all the above right-hand side functions into one as a minimization function. NameOfYourFunction()=
