两数据交换的快速递归算法

A fast recursive algorithm for swapping two data

内存中成块数据的交换已有一般的递归算法，但效率不高．作者提出了一种快速递归算法，极大地提高了效率。

There are several algorithms to swap two mass of data in computer memory,their efficiency isn't very high . However, this paper provides a fast recursive algorithm that improves the efficiency greatly and is more practical in mass data swapping especially.
