递归(recursion)就是在算法中调用自身的一种方法。可以用英文来描述递归,比如:- A function that calls itself is said to be recursive. (调用自身的函数被称为递归的。)- Recursion is an essential concept in computer science and programming. (递归是计算机科学和编程中必不可少的概念。)- The recursive approach may be simpler or more elegant than an iterative one. (递归方法可能比迭代方法更简单或更优雅。)- Recursion can lead to a stack overflow if not implemented properly. (如果没有正确实现,递归会导致堆栈溢出。)无论是在计算机科学还是日常生活中,递归都是一个很重要的概念。
