读写U盘的源程序

用泰勒方法 和 李查逊加速外推法 实现1-100之间的ln(x)计算。其中加减乘除由自己编程实现，因此不受计算机数值变量存储位数的影响。计算精度可以自己规定。几十位左右的精度时可保持计算稳定。

题目    The 15-puzzle has been around for over 100 years; even if you don"t know it by that name, you"ve seen it. It is constructed with 15 sliding tiles, each with a number from 1 to 15 on it, and all packed into a 4 by 4 frame with one tile missing. Let"s call the missing tile "x"; the object of the puzzle is to arrange the tiles so that they are ordered as:   1  2  3  4  5  6  7  8  9 10 11 12 13 14 15  x where the only legal operation is to exchange "x" with one of the tiles with which it shares an edge. As an example, the following sequence of moves solves a slightly scrambled puzzle:
