这是一个JPEG图像编码及解码的程序。它不使用级别…
This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

设有n个人站成一圈,每个人持有一个密码(正整数)。现从第t个人开始,按顺时针方向“1,2,3,4,…”循环报数,数到m1(第t个人所持密码)的人出列,然后从出列者的下一个人重新开始报数,数到m2(刚出列者所持密码)的人又出列,如此重复进行,直到n个人都出列为止。
问题是:对于任意给定的n个人的原始排列顺序,求出n个人的出列顺序。
输入数据从文本文件“实习1数据.txt”中读取。该文件有两行:第1行只有一个整数,表示报数的起始位置;第2行是n个所持密码。
输出结果显示在屏幕上。
