题目:http://www.spoj.com/problems/BALNUM/en/题意:找出区间[A,B]内所有奇数字出现次数为偶数,偶数字出现次数为计数的数的个数。分析:明显的数位dp题,首先,只有3种状态(0:没出现过,1:数字出现奇数次,2:数字出现偶数次),所以,0~9出现的次数就可以用3进制表示,最大的数就是310 ,那么我们就可以把1019 哈希到310 内了。其中,我们可以假设:(

传送门题目大意:一个数被称为是平衡的数当且仅当对于所有出现过的数位,偶数出现奇数次,奇数出现偶数次。给定A,B,请统计出[A,B]内所有平衡的数的个数。注意,这里的偶数是指出现过的数,并且不能计算前导零。蒟蒻一开始理解成所有的偶数和奇数,被坑成狗QAQ对于每一个数有三种状态:0:这个数还木有出现过。1:这个数出现过奇数次。2:这个数出现过偶数次。于是乎用一个三进制数来表示每一种状态,然后直接转移吧
