Description Katu Puzzle is presented as a directed graph G(V, E) with each edge e(a, b) labeled by a boolean operator op (one of AND, OR, XOR) and an integer c (0 ≤ c ≤ 1). One Katu is solvable if one can find each vertex Vi a value Xi (0 ≤ Xi ≤ 1) s…

题目链接 题意:给出a, b, c 和操作类型 (与或异或),问是否满足所有的式子 主要是建图: 对于 and , c == 1: 说明 a 和 b都是1,那么 0 就不能取, a' -> a , b' - > b ,因为 a 和 a'是对立事件,对于 a' - >a说明,a'如果成立,那么a也一定存在,显然这是不可能的所以a'不会 成立的. c == 0 说明 a 和 b不全为1, a' -> b , b' -> a 对于 or, c == 1 :说明 a 和 b 不全为…
