Using queues to implement a stack 10 points; individual-only in lecture, we considered two implementations of the stack adt: one using an array and one using a linked list. devise a third implementation of the stack adt that uses two queues, q1 and q2. use pseudocode to describe how you would use q1 and q2 to implement the stack operations push, pop, and peek, and give the running time of each operation using big-o notation. explain briefly how you came up with the big-o expressions that you use. your algorithms for these methods may use q1, q2, and a constant number of additional variables (either fields of the stack object or local variables of the method). they may not use an array, linked list, orbther data structure. you may assume that the queues support the operations in our queue interface, and that they can store an arbitrary number of objects of any type.

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.
