215. Kth Largest Element in an Array (have better solution )

标签：int   distinct   style   for   ica   back   not   vector   and   

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.

Solution 1:

1 class Solution {
2 public:
3     int findKthLargest(vector<int>& nums, int k) {
4         int n=nums.size();
5         sort (nums.begin(),nums.end());
6         return nums[n-k];
7     }
8 };
