Consider the Edit Distance problem from the Chapter 15 lecture slides. Redo the analysis that led to the recursion equation as in the lecture slides, but with the following two assumptions: 4. In addition to edits possibly being inserts, deletes, or replacements, there is a fourth type of edit, a "swap". This is a swap of two contiguous letters within a word. It counts as one edit, just as do the other three types. Assume that the cost to do different edits is different. In particular, assume that o "d" is the cost to do a delete o "T" is the cost to do an insert o "T is the cost to do a replacement "s" is the costs to do a swap Come up with an equation for this case equivalent to the one we came up with in class, which was TG-1,k)+1 T(j,k) = min
