leetcode215Kth 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.
簡単な問題なら,余計なことは言わない.
class Solution {
public:
    int findKthLargest(vector<int>& nums, int k) {
        sort(nums.begin(), nums.end());
        return nums[nums.size() - k];
    }
};
