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 Example 2:Input: [3
分区达到的效果就是下边的样子。 原数组37615如果把5作为分区点,那么数组最后就会变成下边的样子,i指向最终的分区点76513^i 代码的话,分区可以采取双指针,i前边始终存比分区点大的元素。 publicintfindKthLargest(int[]nums,intk){returnfindKthLargestHelper(nums,0,nums.length-1,k);}privateintfindKthLargestHel...
class Solution { public: int findKthLargest(vector<int>& nums, int k) { int left = 0,right = nums.size(); while(true){ int pos = partition(nums, left, right); if(pos == k-1) return nums[pos]; if(pos > k-1) right = pos; else left = pos+1; } } int partition(vector<...
解法一:直接利用sort函数排序后,取第k大的元素。 classSolution {public:intfindKthLargest(vector<int>& nums,intk) { sort(nums.begin(), nums.end());returnnums[nums.size() -k]; } }; classSolution {public:intfindKthLargest(vector<int>& nums,intk) { sort(nums.begin(), nums.end(),great...
详见:https://leetcode.com/problems/kth-largest-element-in-an-array/description/ Java实现: 方法一: class Solution { public int findKthLargest(int[] nums, int k) { int n=nums.length; if(n<k||nums==null){ return -1; } int low=0; ...
Write a Scala program to compute the average value of an array element except the largest and smallest values. Sample Solution: Scala Code: objectscala_basic{defmain(args:Array[String]):Unit={vararray_nums=Array(5,7,2,4,9);println("Original array:")for(x<-array_nums){print(s"${x},...
The disk drive provides a method of adaptively managing a cache segment divided into chunks by defining an unavailable data type to be stored in an element of a chunk array which indicates that the chunk is not available, and defining an available data type to be stored in an element of ...
第k大的数 = 第len-k+1小的数 len=end+1 然后实际是找第k-1索引处的数 , 因此为end+1-k+1-1 (其实这里的定义有点混乱了 , 不管怎样第一次Accepted了 , 之后再改进 ) LeetCode Kth Largest Element in an Array 结果 funcpartition(nums[]int,startint,endint)int{p:=start ...
冒泡排序 两两比较,把最大的放在最后,然后次大的放倒数第二,依次执行。。。 classSolution:deffindKthLargest(self,nums,k):""" :type nums: List[int] :type k: int :rtype: int """foriinrange(len(nums)):forjinrange(len(nums)-i-1):ifnums[j]>nums[j+1]:nums[j],nums[j+1]=nums[j...
You work with an array of JSON objects read from stdin, filter them using JavaScript to produce a results array that is printed to stdout. jsed - jsed is a small command-line utility to add, remove, and search for data in a JSON structure. jshon - Jshon is a JSON parser designed ...
