Describe оr write pseudоcоde for аn аlgorithm thаt, given a set ( S ) of ( n ) unordered positive integers, determines whether there are two identical elements in ( S ). Your algorithm should run in ( Theta(n log n) ) time in the worst case. You may use any of the algorithms studied in class by including its name as part of the algorithm. if it completes a certain step of the solution. However, the used algorithm time cost must be included in the solution total cost. Your description may be written in plain English or pseudocode.
