python 函数式编程尾递归优化 day16
函数编程的特征： 1不可变：不用变量保存状态，不修改变量 #非函数式
a = 1
def incr_test1():
global a#一旦更改全局变量后后面再调用a就容易乱
a += 1
return a
incr_test1()
print(a) def bar():
print('from bar')
def foo():
print('from foo')
return bar
n = foo()
n() return可以返回任何数值，包

《算法图解》之选择排序
讲述内存中的基础数据结构，数组擅长找元素，链表擅长找位置，为了适应对数据不同的操作要求，应当灵活使用。 1. 内存的工作原理 计算机内存犹如有很多抽屉的柜子. 2. 数组和链表 数组中元素的位置称为索引 元素xx位于索引xx处 数组与链表不同操作对应的时间复杂度 3. 选择排序 定义:遍历这个数组,取出最大的元素添加到新数组中并在元数组中删除这个最大元素,再次遍历这个数组...直到原数组为空 Python实现选择排序 def findSmallest(arr):
