XOR-distance 很显然的按位考虑,按位考虑之后,求式就变成了a和b的每一位与x异或后相加减 对于大于r的位i(指>>2i>r),显然xi只能为0 对于之后的i,我们按照数学归纳法证明贪心,假设我们已经考虑到了第i位,之前的答案有一个正负号 那么由于>>2c>∑i=0c−12i,我们这里想要填的xi一定是想与前面的答案异...
⊕⊕ is the operation of bitwise XOR, and ∣y∣∣y∣ is absolute value of yy. The first line contains a single integer tt (1≤t≤1041≤t≤104)— the number of test cases. Each test case contains integers aa, bb, rr (0≤a,b,r≤10180≤a,b,r≤1018). For each test case, outp...
XOR-distance 目录 问题概述 思路想法 参考代码 问题反思 问题概述 给出整数a、b、r,要求输出|(a^x) - (b^x)|的绝对值,其中0<=x<=r(取值都是[0, 1e18]) 思路想法 首先是一个位置关系,由于求的是绝对值,所以我们可以假定a > b;第二,我们要做的是异或操作,因此可以将a和b的二进制数写出来,结合...

A popular approach is based on the idea of using random XOR constraints to, roughly, successively halving the solution set until no model is left: this is checked by invocations to a SAT solver. The effectiveness of this procedure hinges on the ability of the SAT solver to deal with XOR ...
