POJ 1426 Find The Multiple 题意:给定一个整数n,求n的一个倍数,要求这个倍数只含0和1 参考博客:点我 解法一:普通的BFS(用G++能过但C++会超时) 从小到大搜索直至找到满足条件的数,注意最高位一定为1 假设 n=6  k即为当前所求的目标数,不满足条件则进一步递推 (i 为层数(深度),在解法二的优化中体现,此时可以不管) 1%6=1 (k=1) i=1 { (1*10+0)%6=4 (k=10) i=2 { (10*10+0)%6=4 (k=100) i=4…

POJ.1426 Find The Multiple (BFS) 题意分析 给出一个数字n,求出一个由01组成的十进制数,并且是n的倍数. 思路就是从1开始,枚举下一位,因为下一位只能是0或1,故这个数字只能是1 * 10或者1 * 10 + 1.就按照这种方式枚举,依次放入队列,如果是其的倍数,就输出. 一开始没理解题意,以为是找一个能整除的二进制数,错了半天. 代码总览 #include <cstdio> #include <cstring> #include <algo…
