清华算法课同学课堂上做的讲座，ppt详细讲解了快速排序的原理和算法，cpp文件时详细的算法实现，并附有自己写的随机数据文件生成器-Tsinghua algorithm class students do in class lecture, ppt explained in detail the principles and algorithms quicksort, cpp file, the algorithm in detail, together with random data file

这是一个快速排序的算法源程序，算法被单独写成一个函数，希望对大家有用-This is a quick sorting algorithm source code, algorithms are written as a single function, we hope to be useful
