Ultraviolet A 1156-pixel shuffle Question Link Question: Based on the Transformation Method in the question, given a string of transformation methods, the question needs to be executed several times before the original image can be restored. Train of Thought: the disgusting ratio of this question. First, simulate and find the corresponding matrix after a transformation, and then find all the cycle lengths for this matrix.

This algorithm has two versions, the same principle: Version 1: For (INT I = N; I> = 1; -- I) {Int J = rand (I); // generates a random number exchange (A [I], A [J]); // exchange a [I], a [J]} Version 2: For (INT I = 1; I A calculation process of version 1 is as follows: Ra
