重复提交,这是一直以来都会存在的问题,当在网站某个接口调用缓慢的时候就会有可能引起表单重复提交的问题,不论form提交,还是ajax提交都会有这样的问题,最近在某社交app上看到这么一幕,这个团队没有做重复提交的验证,从而导致了数据有很多的重复提交,在这里我们不讨论谁对谁错,问题解决即可. 首先的一种方式,在前端加入loading,或者是blockUI,在ios以及安卓上也是类似,效果如下: 这个时候整个页面不能再用鼠标点击,只能等待请求响应以后才能操作 具体可以参考blockUI这个插件 此外…

搞死人的题目,,, 就是在n*n的方格中找路径长度为L的回路. 开始的思路值适合n为偶数的情况,而忽视了奇数的case,所以wa了一次. 然后找奇数case的策略,代码从70多行变成了100多,然后改了又改,自己在下面测了好久,交上去1y,但心里却无成就感. 这样的一个题目,提不上什么思路,可以算作是乱搞的,下次比赛中再次碰到类似甚至同样的题目,我并不能保证能写出来. 代码如下: #include <cstdio> #include <cstring> #include <c…

近几年,免疫疗法的成功使癌症治疗进入了新的时代.无论是科研界,还是商业界,都丝毫没有掩饰对这一领域的热情.2016年,Cell杂志公布的年度十大最佳论文中,免疫疗法占两席.事实上,这两项成果只是去年癌症免疫疗法重要突破进展中的“冰山一角”. 刚刚过去的2016年,科学家们在Cell.Nature.Science.NEJM等杂志上发表了大量研究进展,揭露了肿瘤细胞“对抗”免疫细胞攻击背后的不同机制,开发了一系列新型免疫疗法(如调节胆固醇等),找到了癌症免疫疗法只对部分患者有效的多项证据,发现了可用…

假设我们可以对每个位置快速维护一个数组,记录每个位置有哪些值是已经出现了的,哪些值是没有出现的,这样就可以决定修改的时候到底是 *2 还是 +1了. 但是很可惜,并不存在功能这么强大的数组,所以只能另寻方法啦.... 因为修改总是连续的一段的,所以我们可以发现,对于每个数值来说,被它覆盖的位置也是一段一段的,并且所有数的段数之和<=总的操作数(因为还会发生一些段的合并). 所以我们可以对每个数维护一个端点集合set,每次修改的时候就暴力插入一段区间,看一看可以产生多少次合并. 这样的话,虽然一次…
