个人学习图算法时写的源码 包括最小生成树, 最大网络流, DSF遍历, BSF遍历,

evaluates the Black-Scholes formula for a European ca-evaluates the Black-Scholes formula for a European call

实用数据结构基础（第三版），实验七，标识符树与表达式求值-Based the practical data structure (third edition), experimental seven, identifier tree and expressions are evaluated

算法用来计算两个时间序列 x 和 y 之间的距离。-Calculates the distance between two time series x and y. If the distance is larger than the best so far (bsf) it stops computing and returns the approximate distance. To get exact distance the bsf argument should be omit

利用contor函数和BSF实现的魔块问题（游戏）-Use magic block problem (game) contor functions and BSF implemented
