SUNDAY 算法描述：字符串查找算法中，最著名的两个是KMP算法（Knuth-Morris-Pratt)和BM算法（Boyer-Moore)。两个算法在最坏情况下均具有线性的查找时间。但是在实用上，KMP算法并不比最简单的c库函数strstr()快多少，而BM算法则往往比KMP算法快上3－5倍。但是BM算法还不是最快的算法，这里介绍一种比BM算法更快一些的查找算法。例如我们要在"

pay attention to n and the string.it is easy to understand the code below.class Solution {public: string countAndSay(int n) { // Start typing your C/C++ solution below // DO

基本就是遍历的过程中不断的用hash表进行判断，然后不断的维持着这个仍然在范围内的集合。class Solution {public: bool containsNearbyAlmostDuplicate(vector& nums, int k, int t) { map m; int j = 0; for (int i = 0; i

easy problempublic class Solution { public boolean containsDuplicate(int[] nums) { if(nums.length<2) return false; Arrays.sort(nums); for(int i = 1;i<nums.lengt

map是一个接口而hashmap是它的一种实现方式for  this problem, if you use eclipse,you will find that we need a () after the fucthion "new";another should be pay attention is when I use eclipse as the edcitior

This is really a classic problem, no more word need for this.class MyQueue { Stack stack1 = new Stack(); Stack stack2 = new Stack(); // Push element x to the back of queue. public void push

Just use the thought of Bubble sort.I think it would have an O(n) algriothm, I would try it later.public class Solution { public void moveZeroes(int[] nums) { for(int j = 0;j < nums.length
