上一次接触 project euler 还是2011年的事情,做了前三道题,后来被第四题卡住了,前面几题的代码也没有保留下来. 今天试着暴力破解了一下,代码如下: (我大概是第 172,719 个解出这道题的人) program 4 A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.
When you publish your ASP.NET project to a hosting account such as GoDaddy, you may run into the issue below. This issue may occur even though your code works fine in localhost. Server Error in ‘/’ Application. . Parser Error Description: An error oc
今天在C代码中使用gets()时提示“warning: this program uses gets(), which is unsafe.”,然后这个程序还能运行,无聊的我开始查阅资料,为啥gets()会unsafe呢. 通过Google查阅前辈的问答,原来是这么回事. gets()这个函数只有一个参数,那就是字符缓冲区的指针,并没有指定该缓冲区的长度也就是大小.当你输入一个很长很长的字符串的时候,gets ()函数会把每一个字符都存入到栈(statck)中,因此当字符串很大的时候就会导致程序

启动vmware时出现以下错误: Cannot open the disk 'D:\Program Files\VMOS\Centos.vmdk' or one of the snapshot disks it depends on. 原因: 出现这种情况一般是由于上次在关机的出现了异常,比方说非正常关机,强关机等情况,从而导致产生了一些lck为后辍名的文件,那么解决方法就是删除这些lck文件即可. 解决方法 ,D:\Program Files\VMOS\ 目录,删除所有的lck文件即可.
