Description: 1. 一条通路的二元组（i, j）数据序列，（i, j）表示通路上某一点的坐标。
2. 用一种标志（如数字8）在二维数组中标出该条通路，并在屏幕上输出二维数组。
3. 可以利用一个二维数组maze[i][j]表示迷宫，其中1<=i<=m,1<=j<=n。数组元素值为0表示该位置是墙壁，不能通行；元素值为1表示该位置是通路。假定从maze[1][1]出发，出口位于maze[m][n]，移动方向可以是8个方向（东，东南，南，西南，西，西北，北和东北。(1. the two tuple (I, J) data sequence of a path (I, J) indicating the coordinates of a point on the path.
2. mark the path in a two-dimensional array with a sign (such as number 8) and output a two-dimensional array on the screen.
3. can use a two-dimensional array maze[i][j] represents the maze, where 1<=i<=m, 1<=j<=n. The element value of the array is 0, indicating that the location is a wall and cannot pass; the element value is 1, indicating that the location is the path.

Description: FFT，即为快速傅氏变换，是离散傅氏变换的快速算法，它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。它对傅氏变换的理论并没有新的发现，但是对于在计算机系统或者说数字系统中应用离散傅立叶变换，可以说是进了一大步。(FFT, that is fast Fourier transform, is a fast algorithm for discrete Fourier transform. It is based on the odd, even, imaginary, real and other characteristics of discrete Fourier transform, and the algorithm of discrete Fu Liye transform is improved. It does not make new discoveries about the theory of Fourier transform, but it can be a big step for the application of discrete Fu Liye transform in computer system or digital system.
Let x (n) is a complex sequence of N, by DFT transform, either X (m) calculations are N times N-1 times complex multiplication and addition, and a complex multiplication is equivalent to four times the number of multiplication and two real addition, a complex addition is equivalent to two times the number of addition,)

Description: 首先将该程序命名为RSana.m保存，以供调用。
在matlab中导入所要分析的时间序列,保存为x。
然后在matlab命令行输入命令logRS=RSana(x,n,"Hurst")。其中x就是该时间序列，它本身就是向量数据;n为分析的时间周期，Hurst是分析方法。返回值logRS。
这里指对一个周期进行分析，返回返回值logRS是一个标量。如果要作log-log图，需要一个循环，分别对n=5:200进行计算logRS。(First, the program is named RSana.m to save for calls.
In MATLAB, import the sequence of time to be analyzed and save as X.)

Description: 描述
某公司在对应聘者做过一轮笔试之后，从中选出n 人继续进行面试，每位应聘者被分配了一个整数ID。
为公平起见，组织者决定利用会议室外的圆桌，按以下方法“随机”确定面试顺序：第一个到达的应聘者在圆桌周围任意选择一个位置坐下；此后到达的每位应聘者都从前一应聘者出发，沿逆时针方向围圆桌走过m 人（前一应聘者算作走过的第1 人，同一人可能经过多次），并紧邻第m 人右侧就座；所有应聘者到齐后，从最后到达者出发，绕圆桌以顺时针方向为序进行面试。
这里假定应聘者到达的时刻互异，且相对的就坐位置确定后，左、右两人之间总能插入一把椅子。
试编写一个程序，确定面试顺序。
输入
共2行。
第1行包含两个整数， n和m。
第2行包含n个整数，表示先后到达的n个应聘者的ID。
输出
共1行。以空格分隔的n个整数，分别表示顺次进行面试的应聘者的ID。(After a company has done a written test of the candidate, n people are selected to continue the interview. Each candidate is assigned an integer ID.
To be fair, the organizers decided to use the round table outside the conference room to "randomly" determine the interview sequence as follows: The first candidate who arrives at a random place around the round table sits down; each candidate arrives thereafter Candidates starting from the round table counterclockwise around m people (the previous candidate counted as walking through the first person, the same person may go through many times), and the m-th right seat; all candidates to Qi, starting from the last arrivals, around the round table in order to conduct an interview in the clockwise direction.
Here assume that candidates arrive at different times, and the relative seating position is determined, the left and right can always insert a chair between the two.)

Description: input
The input contains a number of test cases. Each test case is composed of multiple lines. The first line is an integer n two (1<=n 100) and m, n said inbound sequence for 1 to n. M indicates that there is then a m line outbound sequence.
When n, M is 0, the end of the input is indicated.
output
For each outbound sequence, a line of YES is exported, otherwise a line of NO is output

Description: A message from humans to extraterrestrial intelligence was sent through the Arecibo radio telescope in Puerto Rico on the afternoon of Saturday November 16, 1974. The message consisted of 1679 bits and was meant to be translated to a rectangular picture with 23 * 73 pixels. Since both 23 and 73 are prime numbers, 23 * 73 is the unique possible size of the translated rectangular picture each edge of which is longer than 1 pixel. Of course, there was no guarantee that the receivers would try to translate the message to a rectangular picture. Even if they would, they might put the pixels into the rectangle incorrectly. The senders of the Arecibo message were optimistic.(The input is a sequence of at most 2000 triplets of positive integers, delimited by a space character in between. Each line contains a single triplet. The sequence is followed by a triplet of zeros, 0 0 0, which indicated the end of the input and should not be treated as data to be processed.
Input
The integers of each input triplet are the integer m, the numerator a, and the denominator b described above, in this order. You may assume 4 < m <= 100000 and 1 <= a <= b <= 1000.
Output
The output is a sequence of pairs of positive integers. The i-th output pair corresponds to the i-th input triplet. The integers of each output pair are the width p and the height q described above, in this order.)
