backtracking.Considerations for recursion:1. Recursion must have a definite end condition.2. Each time a deeper level of recursion is reached, the problem size should be reduced compared to the previous recursion.3. recursive efficiency is not high, in Python, too many recursive layers can cause stack overflow. Recursive applications:Two-part methodModules: self-with modules, their own modules, third-party modules.How to use the
