我们直接使用java提供的排序算法,又因为默认是从小到大排序,所以将倒数第k个数返回即可。 publicintfindKthLargest(int[]nums,intk){Arrays.sort(nums);returnnums[nums.length-k];} 解法二 我们没必要把所有数字正确排序,我们可以借鉴快排中分区的思想,这里不细讲了,大家可以去回顾一下快排。

题目: 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. ...
In this article, we explained how to find the largest and smallest numbers in an array in Java. The process involves initializing two variables, one for the largest and one for the smallest number, with the first element of the array.
