Recursion is used to perform complex tasks such as tree and graph structure traversals. Popular recursive programming solutions include factorial, binary search, tree traversal, tower of Hanoi, eight queens problem in chess, etc.A recursive program becomes concise, it is not easily comprehendible. ...

Factorial Calculation Example: Let's calculate the factorial of a number using recursion. using System; class Program { static void Main() { Console.Write("Enter a number to calculate its factorial: "); int number = int.Parse(Console.ReadLine()); int factorial = CalculateFactorial(number);...
因为,factorial是一个助记符。解释器将直接将它替换为对应的内容,而不会考虑其语义。这里,factorial的定义中,使用了factorial,然而在使用的时候尚未定义过factorial。这就是为什么Lambda演算不支持递归的原因,因为它本身就没有原生的对于递归结构的支持。所以需要转换思路。我们需要将factorial自身,作为一个参数,传入...
