游程编码(Run Length Code) 一、什么是游程编码 游程编码是一种比较简单的压缩算法,其基本思想是将重复且连续出现多次的字符使用(连续出现次数,某个字符)来描述。 比如一个字符串: 1 AAAAABBBBCCC 使用游程编码可以将其描述为: 1 5A4B3C 5A表示这个地方有5个连续的A,同理4B表示有4个连续的B,3C表示有3...
虽然大家都定义了,但是CPython里貌似只有少数个地方在用,就是顺序容器的构造: 看下list的构造,最核心的估计是这一行 static PyObject * list_extend(PyListObject *self, PyObject *iterable) /*[clinic end generated code: output=630fb3bca0c8e789 input=9ec5ba3a81be3a4d]*/ { ... /* Guess a re...
