recursion
一个纯函数，输出只取决于输入
使用最简单的情况举例，一个递归函数只存在一个递归调用
该递归调用讲函数分成三个部分，
1. 递归基 + 准备部分
2. 递归调用部分
3. 递归调用之后的部分
其中第一部分的 准备部分 可以影响递归调用的参数值
第三可以使用递归返回的值(写的时候可以认为这个值来自未来，或者有些更简单的情况，明显能感受到它就是从后往前在处理)

# CPS + 高阶函数可以将递归改写成尾调用，使用Trampoline即可避免爆栈
def cpsF(x,count):
if x == 0:
count(1)
else:
cpsF(x-1,lambda y:count(x*y))
cpsF(257,print)
