The recursive invocation, as the name implies, calls the function inside the function (itself calls itself), usually using it to calculate the factorial, accumulate, etc. note:-Must have the last default result if n ==0, (cannot always call itself, if there is no possibility of causing a dead loop)-the recursive parame

Function Advancednamespace (where the relationship between the variable name and the value is stored)There are three types of namespaces:A.locals: is a namespace within a function, including local variables and formal parametersB.globals: Global variable, the na

Before we introduce recursive functions, we first introduce the following characteristics of the use of the following recursive functions:1. A recursive function is a function that calls itself inside a function body2. The

Inside the function we can call other functions such as:def say (Great): return Great def Person (name): Print (Say ("Hello"), name) person (" Sandichicks ")Print as follows:>>> Hello SandichicksBut if we call ourselves, this function is a recursive functionFor example, let's calculate factorial n! = 1 x 2 x 3 x ... x n (for example, the factorial of 5:5*

Hanoi: Hanoi (also known as Hanoi) is a puzzle toy from an ancient Indian legend. When great Brahma created the world, he made three diamond pillars,The 64 gold discs are stacked on a pillar from bottom to top in order of size. The great Brahma commanded the Brahman to rearrange the discs from below to the other pillars in order of size.It is also stipulated that the disc cannot be enlarged on the small disc, and only one disc can be moved between the three pillars at a time.Hanoi movement probl

1. Recursive invocation principle: divide and conquer To ask for a large-scale problem, you can:(1) Dividing the original problem into several sub-problems(2) Sub-problem scale is small to a certain program, can be directly solved, that is, the condition of the existence of recursive termination, called recursive export.(3) The sub-problems of the original probl
