Find the kth smallest number in at row and column sorted matrix. Example Given k = 4 and a matrix: [ [1 ,5 ,7], [3 ,7 ,8], [4 ,8 ,9], ] return 5 Challenge KLog(Min(M,N,K))时间复杂度 K是因为要Poll K次并且同时insert K次,Min(M,N,K)是堆的size,insert的时间是Log(MIN(M,N,K)) 思路就…
[题目描述] Find the kth smallest number in at row and column sorted matrix. 在一个排序矩阵中找从小到大的第 k 个整数. 排序矩阵的定义为:每一行递增,每一列也递增. [题目链接] www.lintcode.com/en/problem/kth-smallest-number-in-sorted-matrix/ [题目解析] 寻找第k小的数,可以联想到转化为数组后排序,不过这样的时间复杂度较高:O(n^2 log n^2) +…

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…
Ugly number is a number that only have factors 3, 5 and 7. Design an algorithm to find the kth number such that the only prime factors are 3, 5, and 7. The eligible numbers are like 3, 5, 7, 9, 15 ... Example If k=4, return 9. Challenge O(n log n) or…
[抄题]: 在一个排序矩阵中找从小到大的第 k 个整数. 排序矩阵的定义为:每一行递增,每一列也递增. [思维问题]: 不知道应该怎么加,因为不是一维单调的. [一句话思路]: 周围两个数给x或y挪一位, 如果hash数组没有就添加到minheap中 [输入量]:空: 正常情况:特大:特小:程序里处理到的特殊情况:异常情况(不合法不合理的输入): [画图]: [一刷]: class Pair(没有参数)中要有数据类型.方法Pair(int x , int y, int val) PairComp…
