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 ...
