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. The public multiples of all c

Later, the algorithm was improved. Instead of opening an array, it switched the elements above array a to achieve the shuffling.
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:

Question: given n cards, shuffles them n-1 times and asks if they will change back to the original sequence.
Thought: Perfect shuffling:Suppose there is a1a2a3... anb1b2b3... BN card, set the original position of each card to X, then after a perfect shuffling, the first n cards are respectively to 2 x positions, the last n cards are respectively to 1, 3, 5 .. that is, the position of 2x % (2 n + 1). Therefore, t

You are playing a music player, which uses a random playback mode. When playing a random video, a random value of 1 ~ is generated first ~ And then play the songs in the order of N. After playing all the songs in this sequence, a random 1 ~ N to continue playing.
Now I will give you a playback history. This history is incomplete. I thought it was
Poker1. Define an array that holds 1-52 (52 cards, no big, Little King)Of these, 1 means that the a,2 of spades means that the 2...,13 of spades means the spades K, and 14 means the Red peach ...)2. Randomly arrange the array3. Then average the cards to 4 players (divided into 4 arrays, according to the rules of the licensing)4. Sort the output of each player's poker (according to the suit: spades, Hearts, clubs, squares; then size)April 6--an exercise on the number of algorithms--Poker

.Input Description:Each input file contains the one test case. For each case, the first line contains a positive an integer K (Output Description:For each test case, print the shuffling results on one line. All the cards is separated by a space, and there must is no extra space at the end of the line.Input Example:236 52 37 38 3 39 40 53 54 41 11 12 13 42 43 44 2 4 23 24 25 26 27 6 7 8 48 49 50 51 9 10 14 15 16 5 17 18 19 1 20 21 22 28 29 30 31 32 33 34 35 45 46 47Output Example:S7 C11 C10 C12 S

The website uses three diagrams to describe the shuffle process, map and reduce is our own program, so did not write in these three diagrams, today mainly around the three map we do a simple description and review:
