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.
这道题直接用sort函数就可以了,代码如下:
class Solution {
public:
int findKthLargest(vector<int>& nums, int k) {
sort(nums.begin(),nums.end());
return nums[nums.size()-k];
}
};
