hammer.js 的pinch事件 10C
 这里的pinch事件 alert(evt.type)可以alert出来,但是 进不到 onUIMessage(evt) 方法的 if (evt.type == 'pinchstart' || evt.type == 'pinchend' || evt.type == 'pinchmove') {}里边,但是却能进else if (evt.type == 'pan' || evt.type == 'panstart' || evt.type == 'panend' || evt.type == 'panmove') {} 里,有没有大神指导怎么回事啊


// 触摸按下

var msgType = this.getMsgType(evt); // 事件消息类型
if (msgType == "") {
    return;
}

是不是这里退出了?
alert('|'+evt.type+'|')//增加这个看看输出还是对没有没有
if (evt.type == 'pinchstart' || evt.type == 'pinchend' || evt.type == 'pinchmove') {

Whac-a-Mole 是如何来编写的呢
Problem Description While visiting a traveling fun fair you suddenly have an urge to break the high score in the Whac-a-Mole game. The goal of the Whac-a-Mole game is to… well… whack moles. With a hammer. To make the job easier you have first consulted the fortune teller and now you know the exact appearance patterns of the moles. The moles appear out of holes occupying the n2 integer points (x, y) satisfying 0 ≤ x, y < n in a two-dimensional coordinate system. At each time step, some moles will appear and then disappear again before the next time step. After the moles appear but before they disappear, you are able to move your hammer in a straight line to any position (x2, y2) that is at distance at most d from your current position (x1, y1). For simplicity, we assume that you can only move your hammer to a point having integer coordinates. A mole is whacked if the center of the hole it appears out of is located on the line between (x1, y1) and (x2, y2) (including the two endpoints). Every mole whacked earns you a point. When the game starts, before the first time step, you are able to place your hammer anywhere you see fit. Input The input consists of several test cases. Each test case starts with a line containing three integers n, d and m, where n and d are as described above, and m is the total number of moles that will appear (1 ≤ n ≤ 20, 1 ≤ d ≤ 5, and 1 ≤ m ≤ 1000). Then follow m lines, each containing three integers x, y and t giving the position and time of the appearance of a mole (0 ≤ x, y < n and 1 ≤ t ≤ 10). No two moles will appear at the same place at the same time. The input is ended with a test case where n = d = m = 0. This case should not be processed. Output For each test case output a single line containing a single integer, the maximum possible score achievable. Sample Input 4 2 6 0 0 1 3 1 3 0 1 2 0 2 2 1 0 2 2 0 2 5 4 3 0 0 1 1 2 1 2 4 1 0 0 0 Sample Output 4 2

For simplicity, we assume that you can only move your hammer to a point having integer coordinates. A mole is whacked if the center of the hole it appears out of is located on the line between (x1, y1) and (x2, y2) (including the two endpoints). Every mole whacked earns you a point. When the game starts, before the first time step, you are able to place your hammer anywhere you see fit. Input The input consists of several test cases. Each test case starts with a line containing three integers n, d and m, where n and d are as described above, and m is the total number of moles that will appear (1 ≤ n ≤ 20, 1 ≤ d ≤ 5, and 1 ≤ m ≤ 1000). Then follow m lines, each containing three integers x, y and t giving the position and time of the appearance of a mole (0 ≤ x, y < n and 1 ≤ t ≤ 10). No two moles will appear at the same place at the same time. The input is ended with a test case where n = d = m = 0. This case should not be processed. Output For each test case output a single line containing a single integer, the maximum possible score achievable. Sample Input 4 2 6 0 0 1 3 1 3 0 1 2 0 2 2 1 0 2 2 0 2 5 4 3 0 0 1 1 2 1 2 4 1 0 0 0 Sample Output 4 2

整数点的摩尔编码实现的一个问题,如何利用C语言的编程的实现
Problem Description While visiting a traveling fun fair you suddenly have an urge to break the high score in the Whac-a-Mole game. The goal of the Whac-a-Mole game is to… well… whack moles. With a hammer. To make the job easier you have first consulted the fortune teller and now you know the exact appearance patterns of the moles. The moles appear out of holes occupying the n2 integer points (x, y) satisfying 0 ≤ x, y < n in a two-dimensional coordinate system. At each time step, some moles will appear and then disappear again before the next time step. After the moles appear but before they disappear, you are able to move your hammer in a straight line to any position (x2, y2) that is at distance at most d from your current position (x1, y1). For simplicity, we assume that you can only move your hammer to a point having integer coordinates. A mole is whacked if the center of the hole it appears out of is located on the line between (x1, y1) and (x2, y2) (including the two endpoints). Every mole whacked earns you a point. When the game starts, before the first time step, you are able to place your hammer anywhere you see fit. Input The input consists of several test cases.

No two moles will appear at the same place at the same time. The input is ended with a test case where n = d = m = 0. This case should not be processed.

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
