BJP3 Exercise 7.7: kthLargest

Added by: Whitaker Brand on 2013/04/01

Write a method called kthLargest that accepts an integer k and an array a as its parameters and returns the element such that k elements have greater or equal value. If k = 0, return the largest element; if k = 1, return the second largest element, and so on.

For example, if the array passed contains the values {74, 85, 102, 99, 101, 56, 84} and the integer k passed is 2, your method should return 99 because there are two values at least as large as 99 (101 and 102).

Assume that 0 <= k < a.length. (Hint: Consider sorting the array, or a copy of the array first.)
