HDUOJ1043Eight 八数码问题可以构造解

POJ朴素搜索能过的Eight，到HDU的变态数据就过不去了，然而无论双广还是A*都无法实现statistic里0ms的神迹。Discuss里看到了罗教主的一个回帖——构造解！于是专门向罗教主请教了一下，竟然没看懂他的回答。走亲戚和表弟拿纸片玩了好一会儿，发现了一点蛛丝马迹。构造的方法不止一种，斌仔的就和我的不一样，不过原理是相同的。直接八个数分开说吧：首先给八个位置标号，

HDUOJ Knight Moves解题报告

1.典型的bfs。 2.难点在剪枝部分。有一个记录所走step的数组，记录到每个点所走的步数，如果一个点没走过，放进队列中，如果一个点走过，比较原来这个点的step值和由当前点计算的值，如果大，另其等于当前点的step值+1； 3.这道题犯了超级低级的错误。。。写好了bfs（）函数，结果在main()函数中没有添加bfs();语句，导致调试了好久得不到想要的结果。。。 #in
