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...
Codeforces Round #661 (Div. 3) Binary String To Subsequences 队列 题意: 给你一个01串 要求把他分成不同的子序列 并且子序列中不能有两个相同的数相邻 输出分成最少子序列的个数 并且 输出每个0或者1分别在哪个子序列 思路: 一开始看到这个题,就想到用栈或者队列来模拟这个过程,vector来存答案,但是栈...
Binary String To Subsequences(思维,字符串) 技术标签: 思维 字符串题目链接 题意: 给你一个01字符串,你能将他分为至少多少个相邻数字不同的子字符串,输出个数和每一个位置的字符属于哪个子串。 思路: 每次记录都从一段连续的0或1开始,a数组记录子串编号,b数组记录编号子串结尾为0还是1,对于每一段连续的0...
