题意 给你一个只含有0,1,2的字符串,你可以将"01"变为"10","10"变为"01","12"变为"21","21"变为"12",问通过变换可以得到的字典序最小的串是什么? 题解 一开始天真的以为,我把所有的"10"变为"01",和所有的"21"变为"12"即可.…

You are given a ternary string (it is a string which consists only of characters '0', '1' and '2'). You can swap any two adjacent (consecutive) characters '0' and '1' (i.e. replace "01" with "10" or vice versa) or any two adjacent (con…

题目链接:http://codeforces.com/contest/1009/problem/B 解题心得: 题意就是给你一个只包含012三个字符的字符串,位置并且逻辑相邻的字符可以相互交换位置,就是相邻的01交换,12交换,不可以02交换.最后需要输出字典序最小的字符串. 其实想想就很容易明白在字符串中1是可以随便移动的,所以可以把字符串中的1全删除,就只剩下02两种字符,这两种字符的相对位置不可以改变.然后把所有的1插在第一个02之间. #include <bits/stdc++.h>…

You are given a string ss consisting of exactly nn characters, and each character is either '0', '1' or '2'. Such strings are called ternary strings. Your task is to replace minimum number of characters in this string with other characters to obtain…

题目链接:Balanced Ternary String 题目大意:给一个字符串,这个字符串只由0,1,2构成,然后让替换字符,使得在替换字符次数最少的前提下,使新获得的字符串中0,1,2 这三个字符的数目相同,并且新获得的字符串的字典序要尽可能的小: 直接数组做法:暴力遍历 /* */ # include <bits/stdc++.h> using namespace std; typedef long long ll; int n; ]; string s; int main() { io…

题目描述 A ternary string is a sequence of digits, where each digit is either 0, 1, or 2. Chiaki has a ternary string s which can self-reproduce. Every second, a digit 0 is inserted after every 1 in the string, and then a digit 1 is inserted after every…
