题目地址:https://leetcode.com/problems/kth-largest-element-in-an-array/description/题目描述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.
1.Problem Find thekth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. 题意很简单,找到一个一维数组中的第K大的数并返回。数组中第K大的数也是面试中经常考察的问题。现在就借Leetcode上的这题来详细总结下这个问题的...
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...
刚开始我想到了冒泡排序,然后就用冒泡排序解了一下,代码如下: classSolution{publicintfindKthLargest(int[]nums,intk){for(inti=0;i<nums.length-1;i++){//外层循环控制排序趟数for(intj=0;j<nums.length-1-i;j++){//内层循环控制每一趟排序多少次if(nums[j]>nums[j+1]){inttemp=nums[j];nums[...
https://leetcode.com/problems/kth-largest-element-in-an-array/#/description 解题方法: 解法1: 直接用sort函数排序,再输出对应的数即可。方法比较粗暴,但是也能AC。 解法2: 使用了快速排序的思想,快速排序中有一个步骤叫partition,因为求第k大的数其实是求整个数组排序以后一个固定位置的数(nums.size() -...
https://leetcode.com/problems/kth-largest-element-in-an-array/ 题目: 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] ...
LeetCode 215. Kth Largest Element in an Array(排序) 题目 题意:找到一个数组里第K大的数字。 题解:我们当然可以排序好了,之后,选择第K大的数字。但是这样做一点技术含量也没有。 排序算法选用快排。寻找第K大的数字,不必把数组完全排完序之后,再找第K大。快排中是选取一个数字,把大于它的...
Write a Scala program to get the difference between the largest and smallest values in an array of integers. The length of the array must be 1 and above. Sample Solution: Scala Code: objectscala_basic{defmain(args:Array[String]):Unit={vararray_nums=Array(5,7,2,4,9);if(array_nums.le...
A step-by-step illustrated guide on how to get the indices of the N largest values in a NumPy array in multiple ways.
