1067 试密码 (20分)   当你试图登录某个系统却忘了密码时,系统一般只会允许你尝试有限多次,当超出允许次数时,账号就会被锁死.本题就请你实现这个小功能. 输入格式: 输入在第一行给出一个密码(长度不超过 20 的.不包含空格.Tab.回车的非空字符串)和一个正整数 N(≤ 10),分别是正确的密码和系统允许尝试的次数.随后每行给出一个以回车结束的非空字符串,是用户尝试输入的密码.输入保证至少有一次尝试.当读到一行只有单个 # 字符时,输入结束,并且这一行不是用户的输入. 输出格式: 对用…

题目链接 https://www.patest.cn/contests/pat-a-practise/1065 思路 因为 a 和 b 都是 在 long long 范围内的 但是 a + b 可能会溢出 long long 但是 不会溢出 long double 所以 用long double 就能轻松解决了 或者 用大数加法 也行 AC代码 #include <cstdio> #include <cstring> #include <ctype.h> #includ…
