找出第k大的数。 解法一 暴力 使用快排从大到小排序,将第k个数返回即可。 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

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. 题意:给出...
Kth Largest Element in an Array 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 ≤...

215. Kth Largest Element in an Array 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...
75. Calculate the largest gap between sorted elements in array Write a Java program to calculate the largest gap between sorted elements of an array of integers. Sample Data: {1, 2 ,9, 0, 4, 6} -> 3 {23, -2, 45, 38, 12, 4, 6} -> 15 ...
You may assume k is always valid, 1 ≤ k ≤ array's length. 数组中的第K个最大的元素。 题目即是题意。这个题有几种不同的做法,但是考点应该是用快速排序 quick sort来解决问题。 暴力解。先用Java的内置函数对数组排序然后找出第K大的元素。
Given a set of distinct positive integers, find the largest subset such that every pair (Si, Sj) of elements in this subset satisfies: Si % Sj = 0 or Sj % Si = 0. If there are multiple solutions, return any subset is fine. 题目意思也很简单,给出一个不含重复数字的数组,找到最长的一...
