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。 public int findKthLargest(int[] nums, int k) { Arrays.sort(nums); return nums[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...
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.
