[leedcode 215] Kth Largest Element in an Array

Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element.

For example,
Given [3,2,1,5,6,4] and k = 2, return 5.

Note: 
You may assume k is always valid, 1 ≤ k ≤ array‘s length.

public class Solution {
    public int findKthLargest(int[] nums, int k) {
        //先排序，然后返回第k个值（从小到大排序）
        Arrays.sort(nums);
        return nums[nums.length-k];
    }
}
