For each test case, print the answer: in the first line print one integer k (1≤k≤n) — the minimum number of subsequences you can divide the string s to. In the second line print n integers a1,a2,…an (1≤ai≤k), where ai is the number of subsequence the i -th character of...
D. Binary String To Subsequences(队列)(贪心) 题意:你被给予了一个二进制字符串包含n个零和n个一。你的任务是分割这个字符串为最小的数量的子串,使得这些子串为'010101...'或者'101010...',输出每个字符属于的字符串编号。 分析:一开始想的是,字符个数为o(n),应该是一个线性的时间复杂度或者是o(nlogn...
Everool has a binary string ss of length 2n2n. Note that a binary string is a string consisting of only characters 00 and 11. He wants to partition ss into two disjoint equal subsequences. He needs your help to do it. You are allowed to do the following operation exactly once. You ...
Alright, so this is my 2ndpost here. The 1stone, as you can see, was written in Vietnamese – my mother tounge, just because I thought that CodeForces Blog could be used for my personal purposes and my entry would not be read by anyone else, except me :D Due to that, I’m gonn...
Codeforces Round #661 (Div. 3)D-E1 D. Binary String To Subsequences 题意:一个长度为n的字符串,可以从左到右拆分到多个集合中,保证该集合的前一个字符与后来的字符不同,问最少需要多少个集合。 题解:用两个数组t0和t1分别存储0和1模拟,每个0隶属于它出现时t1数组最后一个1的位置,每个1隶属于它...
(cf)Binary String To Subsequences 题意:将给定字符串分成最少个字串,标明原串中每个字符在第几个子串中(编号),字串不能有连续字符。 题解:遇到0时,因为不连续,后面跟1,此时如果1为空,只能新建一个子串;如果1非空,取一个1放在0后面。...Codeforces D - Binary String To Subsequences(思维 + 数据结构...
