We can guess the first few values and then attack the PRNG to recover the seed and predict next outputs. The simplest solution is to bruteforce all candidates for x, deduce y as xor of PRNG output with x and check if the numbers match. cindy dahl grand forks ndWebTo demonstrate this to the incredulous, generate a million values using the LCG in the question; count how many times each of the 32768 values is reached; and either compute the standard deviation of that, or graph the … cindy daehnkeWeb实例要求： 输入：一行，两个整数n和m（int范围内） ；输出：一行，一个数字，表示n和m的最大素公约数；所谓最大素公约数，就是两个整数的公约数中是素数的… cindy dareWebManaging Partner.
