[CF1553H] XOR and Distance Problem:Problem:XOR and Distance Solution:Solution: 首先策略是,最高一位ai⊕xai⊕x与aj⊕xaj⊕x不同,使得这个最高位最低。然后尽量多的使后面位置ai⊕xai⊕x与aj⊕xaj⊕x不同且符号与最高位相反。 这里普通的做法是利用01trie01trie求解,实现较为复杂。CF 上某位神仙提供了...
So now we duplicate the useful bit of diff_one into the other bit position, by shifting it left by the distance between the two bits, and combining that with diff_one itself to get diff_dup. This has a 1 in both of the target bit positions if the two bits need to be flipped, ...

Model counting is a hard, #P-complete problem. For this reason, many approximate counters have been developed in the last decade, offering formal guarantees of confidence and accuracy. A popular approach is based on the idea of using random XOR constraints to, roughly, successively halving the ...

We settled on an answer based on another crypto 101 concept: The unicity distance. This is the minimum number of ciphertext characters such that the expected number of possible plaintexts is exactly 1; we simply plugged in the given ciphertext length and solved for the key length instead. ...
