Show how to compute the length of an LCS using only 2 · min (m, n) entries in the c table plus O (1) additional space. Then show how to do this using min (m, n) entries plus O (1) additional space.
Answer to relevant QuestionsProfessor Canty conjectures that there might exist some ei, ai,j, and ti,j values for which FASTEST-WAY produces li[j] values such that l1[j] = 2 and l2[j] = 1 for some station number j. Assuming that all transfer costs ti, ...Give asymptotic upper and lower bounds for T(n) in each of the following recurrences. Assume that T(n) is constant for n ≤ 2. Make your bounds as tight as possible, and justify your answers. Suppose that you are given n red and n blue water jugs, all of different shapes and sizes. All red jugs hold different amounts of water, as do the blue ones. Moreover, for every red jug, there is a blue jug that holds the ...During the course of an algorithm, we sometimes find that we need to maintain past versions of a dynamic set as it is updated. Such a set is called persistent. One way to implement a persistent set is to copy the entire set ...In the depth-determination problem, we maintain a forest F = (Ti) of rooted trees under three operations:• MAKE-TREE (v) creates a tree whose only node is v.• FIND-DEPTH (v) returns the depth of node v within its ...
