K - Prime Ring Problem ================================================================================================================================= 题目大意是给出 1~n 个数 第一个数必定是 1 ,使得无论那两个相邻的数相加,都是质数(即大于1的自然数中,除了1和它本身以外不再有其他因数): 打印出所有可能,即直接用dfs 遍历所有可能性…

http://acm.hdu.edu.cn/showproblem.php?pid=1016 题意:输入n,代表有一个包含n个节点的环,在环中的节点中填入1,2...n-1,n,要求填入的数与左边的数之和,与右边的数之和,都为素数 输出所有符合要求的环(第一个数总为1) 用DFS模拟,从第2位到第n位依次选取一个与上一个选取的数之和为素数的数 直到选取完第n个数,判断第n个数和1之和是否为素数,是则输出,否则不进行操作,判断完毕返回上一层 直到遍历完所有情况 *:因为素数必然是奇数,所以一条符合…

A ring is compose of n circles as shown in diagram. Put natural number 1, 2, ..., n into each circle separately, and the sum of numbers in two adjacent circles should be a prime. Note: the number of first circle should always be 1. Inputn (0 < n < 2…
