思路来自紫书...开始时的思路估计100行+,果断放弃!关键:1.正确提取出函数!   initmap():初始化字母与整数的映射.   returnint(x):向后读取x位,并转换为十进制数返回.   enterfilter():获取下个字符,跳过回车.   所以,   不断initmap()构建映射表直到结尾:   对于每组编码表,   使用returnint(x)一直读取并返回:   这其中又涉及到回车的干扰,所以使用enterfilter().2.逐个字符读取的应用.   其实还很方便…

POINT: 关于表示一个编码:利用code字符数组表示一个编码字符,其中code[len][val]表示长度为len,二进制值为val的字符: 主程序如下: #include <iostream> #include <sstream> #include <cstdio> #include <cstring> #include <cmath> #include <string> #include <vector> #inc…

题意:阅读理解难度一道比一道难orz.手摸了好久样例 题解: 读入:大循环用getline读入header顺便处理一下,  里面再写两重循环,外层一次读三个串,内层一次读num个串. 之后就查表,线性输出即可. 关于判断11111,我用了换底公式:log(id + 1) / log(2) == num + 1 && pow(2, log(id + 1) / log(2)) 关于读入,我写了个getnchar的函数,封装一下getchar() 虽然是final模拟(签到orz)题,码量不大嘛…
