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
# @param {Integer[]} nums
# @param {Integer} k
# @return {Integer}
def find_kth_largest(nums, k)
n = nums.length
nums.sort!
nums[n - k]
end
