You are interested in analyzing some hard-to-obtain data from two separate databases. Each database contains n numerical values—so there are 2n values total—and you may assume that no two values are the same. You’d like to determine the median of this set of 2n values, which we will define here to be the nth smallest value. However, the only way you can access these values is through queries to the databases. In a single query, you can specify a value k to one of the two databases, and the chosen database will return the kth smallest value that it contains. Since queries are expensive, you would like to compute the median using as few queries as possible. Give an algorithm that finds the median value using at most O(log n) queries.
Use the Divide and Conquer Algorithm Design Technique to design an efficient algorithm for Matrix Multiplication. Determine the time complexity of your solution.
Hope this may help you
If u need much more than this just leave a comment I will try to provide
Thank you ??

(25pts) You are given two sorted lists of size m and n. Give an O(log m log n) time algorithm for computing the k-th smallest element in the union of the two lists Note that the only way you can access these values is through queries to the databases. Ina single query, you can specify a value k to one of the two databases, and the chosen database will return the k-th smallest value that it contains. Since queries are...
Part I. Create a library check-out database using Microsoft SQL Server that stores data about books, patrons, and the check-out process. Books (BookID, BookName, Author, YearPublished) Patrons (PatronsID, PatronsName, PatronsAddress, PatronsBirthday) CheckInOut (TransactionID, PatronID, BookID, CheckOutDate, NumDay, ReturnDate, Late, Fees, Paid) - the NumDay field contains the number of days patrons can keep the book, if the return date is over the number of day, then the Late field will have a Y value and a fee of $1.00 per...
