利用三次样条插值法求曲线在某个点处的函数值-Using cubic spline interpolation method demand curve at some point of the function values

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.
