素数环： 把从1到10这10个数摆成一个环，要求相邻的两个数的和是一个素数。 〖问题分析〗 这是一道回溯的题目。从1开始，每个空位有9种可能，每种可能加入约束条件即可
1.与前面所有的数不重复
2.与前一个数和为素数（最后一个和第一个也要满足）。 〖算法流程〗 1、数据初始化； 2、递归填数： 判断第J种可能是否合法； A、如果合法：填数；判断是否到达目标（10个已填完）： 是，打印结果；不是，递归填下一个； B、如果不合法：选择下一种可能；-Prime Central: 1-10 from 10 the number of put this into a ring, asked the two adjacent numbers and is a prime number. 〗 〖Analysis is a retrospective this topic. From 1 year, 9 out of every space possible, each may be bound by the conditions of accession to 1. And in front of all the number of non-repetition, 2. With a few and for a prime number (the last and the first to meet). 1〗 〖algorithm processes the data to initialize 2, fill in the number of recursion: first to determine the legality of J possible A, if the legitimate: the number of Reclamation to determine whether the target (10 have been completed): Yes, print the results of not, fill in the next recursive B, if not legitimate: a possible alternative
