哎，哎，哎。本来以为很简单的题，结果还是WA了一次，RE了两次。题目看似复杂，其实本身很好理解。把' '看成0，‘o’看成1。就是二进制的ascii码。但是，千万不要用数组储存输入，会超时。解决方法就是用getchar()一个一个读取，读满8个就putchar()出来。还有，不能仅用换行符当作输出的判断条件。不然读到第一行和最后一行的时候会输出空字符'\0'。尤其在terminal下，空字符被隐藏起来了。在windows上的命令符貌似是一个空格。oj系统是可以识别出来的。现在编程能力真是挫的一比啊。题目： Problem ADecode the tapeTime 阅读全文

说起来感觉自己弱爆了，这道题成了一道跨年题。因为学校考试复习吧，于是拖到现在才AC。以后要抓紧努力了，好久没敲代码开始手生了。本来前一段时间是存着WA的代码的，结果重装Ubuntu就没了。于是WA的原因至今也不清楚，不过参考题解，以后把字符串转换为浮点型储存的时候还是灵活使用math.h里面的数学函数吧。总之，terry要好好努力了，这个状态下学期就是要被虐得满身疮夷了。题目： Artificial Intelligence?Physics teachers in high school often think that problems given as text are more dema 阅读全文
