Suppose we have two transmitters, each of which sends out repetitions of some short string. For example, transmitter 1 may repeat string x=101 over and over, so what we will hear from it will be a prefix of x k - that is, x concatenated to itself k times, possibly with a few bits chopped of the end (as in 10110110). Transmitter 2 repeats another string, y. Our job is to determine if a sequence s that we have heard is an interleaving of these two transmissions. For example, suppose transmitter 1 repeats x=101 and transmitter 2 repeats y=01. The sequence 010111010101 can be unraveled into x and y: positions 1, 5, 9, and 12 contain 0101, a repetition of y, while the remainder of the string contains 10110110, a repetition of x. Describe an efficient algorithm which takes a sequence s of length n, and two strings x and y, and determines if s is an interleaving of repetitions of x and y.
For this dynamic programming problem and the next one, be sure to
(a) describe the subproblem
(b) give a recurrence for the subproblem
(c) provide pseudo-code showing how a table for the subproblems is filled
(d) give the time and space requirements of your method

it is much more convenient for the consumer to order something online, rather than going to a store. it saves them time and money for them, especially if that item is not accessed easily.

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
