题意:一个码如果是另一个码的前缀,则 is not immediately decodable,不可直接解码,也就是给一串二进制数字给你,你不能对其解码,因解码出来可能有多种情况. 思路:将每个码按长度从短到长排序,逐个与其后面的码比较,若前面相同位数完全一样了,那就可以输出了. #include <iostream> #include <stdio.h> #include <string> #include <map> #include <cstri…

题目大意:输入一系列的字符串,判断这些字符串中是否存在其中的一个字符串是另外一个字符串的前缀.. 如果是,输出Set .. is not immediately decodable 否则输出Set .. is immediately decodable 说的通俗点,就是判断一个字符串是否是两外一个字符串的前缀 解题思路: 这是一道字典树的题.一开始的时候,我用c/c++来写,然后是100行写完了,就是不知道哪里错了 这时,我实在忍不住了.直接就用java来写了 代码如下:(注意以下代码在subm…

求这些01串是否有一个是另一个的前缀.. 就是求次数就好了嘛...emm... 网上竟然都用指针写.... #include<cstdio> #include<iostream> #include<algorithm> #include<cstring> #define maxn 2000010 #define mem(a, b) memset(a, b, sizeof(a)) using namespace std; int tot, n, m, rt;…
