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 ...
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排。 随机选择一个分区点,左边都是大于分区点的数,右边都是小于分区点的数。左部分的个数记...
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...
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] Note: You may assume k is always valid, 1 ≤ k ≤ array's length. ...
Description 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. Example 1: Input: [3,2,1,5,6,4] and k = 2 Output: 5 1. 2. Example 2: ...

second_largest_values = nums[indices, np.arange(nums.shape[1])]: This line creates a new array second_largest_values by indexing nums using the row indices in indices and column indices created by np.arange(nums.shape[1]), which returns an array of integers from 0 to the number of col...
