215. Kth Largest Element in an Array
Medium
Given an integer array nums and an integer k, return the kth largest element in the array.
Note that it is the kth largest element in the sorted order, not the kth distinct element.
Example 1:
Input: nums = [3,2,1,5,6,4], k = 2
Output: 5
Example 2:
Input: nums = [3,2,3,1,2,4,5,5,6], k = 4
Output: 4
Constraints:
1 <= k <= nums.length <= 104-104 <= nums[i] <= 104
Solution
import scala.util.Sorting
object Solution {
def findKthLargest(nums: Array[Int], k: Int): Int = {
val n = nums.length
Sorting.quickSort(nums)
nums(n - k)
}
}
