题意: 一个字符串含有两个相邻的重复的子串,则称这个串为容易的串,其他为困难的串,对于给定n,l,求出由前l个字符组成的字典序第n小的困难的串. 分析: 按字典序在字符串末尾增加新的字符,并从当前字符串后缀入手,判断长度为偶数的子串中,是否含有重复的相邻子串. 代码: #include<cstdio> #include<iostream> using namespace std; int n, l, cnt; int s[85]; int dfs(int cur) { if(cnt…

Input and Output In order to provide the Quiz Master with a potentially unlimited source of questions you are asked to write a program that will read input lines that contain integers n and L (in that order), where n > 0 and L is in the range , and…
回溯法:避免无用判断,强化回溯代码的实现过程 题目的大意就是以字典序为准,排列字符串,但要保证一个字符串中不包含相邻的重复子串. Problem Description For example, the sequence ABACBCBAD is easy, since it contains an adjoining repetition of the subsequence CB. Other examples of easy sequences are: BB ABCDACABCAB AB…
