Codeforces Round 872 Div 2 Full Video Editorial Div 1 A C Youtube The idea is simple first of all, imagine two strings, reverse of s1 s 1 and orginal s2 s 2. now everytime you perform an operation, you select a suffix of length k k from both the strings, reverse them and swap them. it simplifies the problem (makes it easier to visualize). Codeforces round #823 (div. 2) a d 比赛链接 a 题解 知识点：贪心。 对于一个轨道，要么一次性清理，要么一个一个清理。 显然，如果行星个数大于直接清理的花费，那么选择直接清理，否则一个一个清理。.
Codeforces Round 832 Div 2 Codeforces Problems Youtube I love doing competitive coding and i surely know the struggles everyone face while learning new concepts. this sole idea gives me the motivation to start this channel , i am still learning and. Codeforces round #823 (div. 2) b. meeting on the line time : o(nlog(1e8)) o (n l o g (1 e 8)) space : o(1) o (1). Planets (签到题)思路分析:有 n 个元素位于不同的轨道上 (可以存在有几个元素位于同一个轨道上),使用一个 map 进行存储后,对于一个轨道内部的损耗进行统计并且与 m 进行比较….
