Suppose you have two data sets, each of which contain n comparable elements. As an basic operation, you may ask one set to tell you the kth largest element of that set, for a value k you choose. Give an algorithm that, with O(log n) queries, determines the median value of the union of the two sets.

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
