这是悦乐书的第241次更新,第254篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第108题(顺位题号是482).您将获得一个表示为字符串S的许可证密钥,该字符串仅包含字母数字字符和短划线.该字符串被N个破折号分成N + 1个组. 给定数字K,我们希望重新格式化字符串,使得每个组包含正好的K个字符,但第一个组可能比K短,但仍然必须包含至少一个字符.此外,必须在两个组之间插入短划线,并且所有小写字母都应转换为大写.给定非空字符串S和数字K,根据上述规则格式化字符串.例…

problem 482. License Key Formatting solution1: 倒着处理,注意第一个字符为分隔符的情况要进行删除,注意字符的顺序是否正序. class Solution { public: string licenseKeyFormatting(string S, int K) { ) return NULL; ; string ans = ""; ; i>=; i--)//倒着处理. { char c = S[i]; if(S[i]=='-') c…

创建一个基于时间的键值存储类 TimeMap,它支持下面两个操作: 1. set(string key, string value, int timestamp) 存储键 key.值 value,以及给定的时间戳 timestamp. 2. get(string key, int timestamp) 返回先前调用 set(key, value, timestamp_prev) 所存储的值,其中 timestamp_prev <= timestamp. 如果有多个这样的值,则返回对应最大的  t…
