地图着色把地图上的每个城市抽象为一个点，并给每个城市编号，，相邻的城市之间用直线连接。据此做出邻接矩阵，若第i个城市与第j个城市相邻，则metro[i][j]=1,否则metro[i][j]=0。 算法：按照编号从小到大的顺序检查每个城市，对每个城市从1到4使用4种颜色着色，若当前颜色可用（即不与相邻城市颜色相同），则着色；否则测试下一种颜色。 -Map coloring to each city on the map as a point of abstraction, and to every city number, adjacent lines to connect between cities. Accordingly to make adjacency matrix, if the section i and section j cities adjacent cities, the metro [i] [j] = 1, otherwise the metro [i] [j] = 0. Algorithm: In accordance with the code sequence from small to large checks every city, every city on 1-4 from the use of four kinds of color shading, color can be used if the current (ie not with the same colors as the neighboring cities), then coloring Otherwise, the next test colors.

在某些软件应用当中需要把某些文件压缩成一个RAR或ZIP或JAR文件，例如手机程序是一个JAR包，因此在手机开发中，某些工具可以提供此功能：把某些文件压缩进某包，本代码即实现此种功能。 在实际应用中，例：游戏开发中，可把某些工具生成的文件（地图文件、脚本文件等)例用本代码将这些文件压缩到游戏jar包中，避免需要程序员进行打包的麻烦，以方便游戏策划人员进行编辑或调试。 主要是复用WAR软件的命令进行压缩-In some software applications which need to be certain files compressed into a RAR or ZIP or JAR files, such as the cell phone program is a JAR package, so mobile phone development, certain tools can provide this functionality: certain files compressed into a certain package, the code that is to achieve such functionality. In practice, example: game development, you can put some tools generated files (map files, script files, etc.) were treated with this code in the files compressed into the game jar package, to avoid the need to package the programmer the trouble of Games planners to facilitate editing or debugging.

实现JPEG的压缩和编码 （1）首先通过DCT变换去除数据冗余； （2）使用量化表对DCT系数进行量化； （3）对量化后的系数进行Huffman编码。 -The realization of JPEG compression and coding (1) First of all, through the DCT transform to remove data redundancy (2) the use of quantization table of quantization DCT coefficients (3) of the coefficients after quantization Huffman coding.
