Google APAC Test 2016 Not So Random 矩阵快递幂(logN复杂度)【代码】【图】

ProblemThere is a certain "random number generator" (RNG) which takes one nonnegative integer as input and generates another nonnegative integer as output. But you know that the RNG is really notvery random at all! It uses a fixed number K, and always performs one of the following three operations:with probability A/100: return the bitwise AND of the input and Kwith probability B/100: return the b...
