题目地址:http://oj.tsinsen.com/A1082 问题描述 给定一个大小为n的数组s和一个整数K,请找出数组中的第K小元素. 这是一个补充程序的试题,你需要完成一个函数: int findKth(int *s, int n, int K) 表示在s指向的数组中找到第K小的元素(如果K=1,表示找最小元素),你需要返回该元素的值. 此题对时间的要求比较高,请注意下面的算法描述. 算法描述 你可以直接将s中的元素进行排序后输出第K小的元素,但使用这种方法你大概只能得到30%的分数.…
Given an integer array, return the k-th smallest distance among all the pairs. The distance of a pair (A, B) is defined as the absolute difference between A and B. Example 1: Input: nums = [1,3,1] k = 1 Output: 0 Explanation: Here are all the pairs:…
Nearly every one have used the Multiplication Table. But could you find out the k-th smallest number quickly from the multiplication table? Given the height m and the length n of a m * n Multiplication Table, and a positive integer k, you need to ret…
A sorted list A contains 1, plus some number of primes. Then, for every p < q in the list, we consider the fraction p/q. What is the K-th smallest fraction considered? Return your answer as an array of ints, where answer[0] = pand answer[1] = q. Ex…

Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5…
Given a binary search tree, write a function kthSmallest to find the kth smallest element in it. Note: You may assume k is always valid, 1 ≤ k ≤ BST's total elements. Follow up: What if the BST is modified (insert/delete operations) often and you nee…
