为绘制分形混浊曲线、Julia集、和Mandelbrot集的程序源代码，程序运行后， 分别选择菜单“分形”下的子菜单“混沌曲线”、“Julia集”或者“Mandelbrot集”，将分别绘制这 几种分形图案。对于Mandelbrot集，可以用托动鼠标选择一矩形框，然后点击鼠标右键对所选择的区域 进行放大。-for mapping turbidity fractal curve, Julia sets, and the Mandelbrot set of program source c

Codes". Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes") (that is, the bit string representing some particular symbol is never a prefix of th
