Both are programming languages similar to C, Java, and PHP. However, since Python and R are both relatively young and "Far Away" from the CPU, they seem simpler. Compared with R, which is only used to process data, such as machine

Bsgs This is mainly used to solve this problem:A^x=b (mod c) (c is prime), are integers, known as a, B, and C for X.In the specific topic, C is generally the total number of all possible events.Solution:Set m = ceil(sqrt(C))（ceil为上取整）, x = i * m + j ,So A^x = (A^m)^i * A^j, (0 .You can then enumerate i the O(sqrt(C)) levels of the enumeration.For an enumeration, the i D = (A^m)^i present problem is translated into a request D * A^j ≡ B (mod C) .If it is A^j regarded as a whole, then the EXGCD c
