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...
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. 这道题拿到...

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<...
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...
给定整数数组nums和整数k,请返回数组中第k个最大的元素。 请注意,你需要找的是数组排序后的第k个最大的元素,而不是第k个不同的元素。 你必须设计并实现时间复杂度为O(n)的算法解决此问题。 示例1: 输入:[3,2,1,5,6,4],k = 2输出:5

The bound is constructed from a centre point, a 2D size and the primary axis (the first element of the 2D size). Extensions.cs This class contains some Vector2 extension methods to simplify the code (Rotate for simple 2D rotations, and F3() to make logging more concise). LargestInterior...
