When we search in Google for "A B C D" this is equivalent to searching for "A AND B AND C AND D", i. e. searching for all documents that contain all four keywords A, B, C and D. We ask you to design an algorithm that does so efficiently. The first thing a search engine does is to generate a hit-list for each keyword. A hit-list is a sorted sequence of document-identifiers (doc-id’s) that contain the keyword in question. Let the hit-lists be in the form of sorted arrays A[1..a], B[1..b], C[1..c], D[1..d] of doc-id’s for the four keywords respectively. Let the lengths of the arrays A, B, C and D be respectively a, b, c, d, where a = n 3 , b = n lg n, c = n 2 and d = n for some parameter n. Give an efficient algorithm that generates the hit-list of doc-ids in which all four keywords A, B, C, D appear; this output hit-list should also be sorted by doc-id. How big is the output hit-list ? Express your answer in asymptotic notation in terms of n with a bound that is as asymptotically tight as possible. Express the running time of your proposed efficient algorithm in terms of n using asymptotic notation (as tight as possible).

Create a file called favorite_foods, and list your favorite foods, entering five or six or more. press enter after each favorite food so it appears on its own line (make certain you also press enter after the final food item). after the file is created, add two more foods you like that are not on the list (press enter after the final food item). view the list of foods to make certain the two items you added appear at the end of the list
