Implement a method to find the second largest number in an array of ints. If the input array is empty or contains only a single number, the method must returnInteger.MIN_VALUE. If the input array contains multiple largest elements, consider them as the same value. Sample Input 1: 1531246 ...
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...
To find the largest element from the array, a simple way is to arrange the elements in ascending order. After sorting, the first element will represent the smallest element, the next element will be the second smallest, and going on, the last element will be the largest element of the arr...
