Given a set of n numbers we wish to find the i largest
Given a set of n numbers, we wish to find the i largest in sorted order using a comparison based algorithm. Find the algorithm that implements each of the following methods with the best asymptotic worst-case running time, and analyze the running times of the algorithms in terms of n and i.
a. Sort the numbers, and list the i largest.
b. Build a max-priority queue from the numbers, and call EXTRACT-MAX i times.
c. Use an order-statistic algorithm to find the ith largest number, partition around that number, and sort the i largest numbers.
