利用深度遍历的方法来检查8数码问题是否有解。

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去掉不满足条件的排列。 2.程序源代码：-topic : 1,2,3,4 figures, the number can be formed with each other with no repeat of the triple-digit figures? How many are? 1. Program Analysis : can fill the 100, 10, 000 the number of spaces are 1,2,3,4. With all the components removed after not satisfied with the conditions. 2. Source code :

有许多是考研要用的！三路归并算法，快速排序的非递归算法，无向连通图的非递归的深度优先遍历等，，希望大家用得着-many are taking tests to use! Three road merging algorithm, rapid sequencing of non- recursive algorithm, undirected graph of the non- recursive depth-first traversal, and we hope that it needs! !

好用啊 ，主要是一些，小列子。你一定要看懂了再用！-handy ah, mainly some small Liezi. You must understand the reuse!
