题目:给出n,求出最小的m,满足m^2  % 10^k = n,其中k=0,1,2 http://acm.hdu.edu.cn/showproblem.php?pid=4394 只要有一个x满足条件便行了 我们可以初步发现,某个数个位确定,那么平方的最后一位肯定是确定的,那么如果后两们确定,那么平方的最后两们也是确定的,这可以通过乘法的规律得到 那我们只需要BFS一下,不断地找满足最后指定位数的数,1位,2位,--直到找到第一个满足条件的. 注意这里可能是100001这种情况 所以记录当前数字大…

容斥原理 A Number Sequence 题意:给出n个数,b1,b2,b3……bn,构造n个数,a1,a2,……an(ai>1),使得a1*a2*a3……an=b1*b2……bn 分析:容易想到的是将bi分解质因数,然后记录每个质因数的个数.那么题目变成:对于(每个质因数个数为m个划分到n个不同的容器的方案数),注意ai>1,所以没有某个数没有质因数.记f(n)为n个数字可能有1的方案数,g(n)为n个数字一定没有1的方案数.则,得到听说这是二项式反演? #include <bit…

Leetcode之深度优先搜索(DFS)专题-473. 火柴拼正方形(Matchsticks to Square) 深度优先搜索的解题详细介绍,点击 还记得童话<卖火柴的小女孩>吗?现在,你知道小女孩有多少根火柴,请找出一种能使用所有火柴拼成一个正方形的方法.不能折断火柴,可以把火柴连接起来,并且每根火柴都要用到. 输入为小女孩拥有火柴的数目,每根火柴用其长度表示.输出即为是否能用所有的火柴拼成正方形. 示例 1: 输入: [1,1,2,2,2] 输出: true 解释: 能拼成一个边长为2的…

Square HDU 1518 搜索 题意 原题链接 给你一定若干个木棒,让你使用它们组成一个四边形,要求这些木棒必须全部使用. 解题思路 木棒有多种组合方式,使用搜索来进行寻找,这里需要进行优化,不然复杂度非常高. 因为M最大为20,所以,如果用DFS还是可以接受的. 由所有火柴棒的长度和,我们可以求出要组成正方形的边长.我们设边长为len.在搜索前,首先可以把边长为分数的,也就是火柴棒的长度和不能被4整除的,排除掉. 问题可以转化为从M个数中挑出4组和为len的数. 首先,从M个数中搜索出和…

题目链接 题意 : 自守数的定义:如果某个数的平方的末尾几位数等于这个数,那么就称这个数为自守数.例如5*5=25,则5就是自守数.让你求不超过n位的自守数有多少 思路 : 实际上,自守数还有两个性质:以他为后几位的两个数相乘,乘积的后几位仍是这个自守数.刚好n位的自守数一定是两个,当然1位的时候0和1是没有算进去的,但是题目中1是要加上的,所以从第0位深搜枚举到第n位.还有另一种方法,因为一个数是自守数当且仅当这个数是另一个自守数的后缀,2000位的自守数只有两个,所以存下来直接数也行 #in…
