根据题目要求使用递归函数，根据题目给定的数学算式，求出Succ(n)的值。可以在每一次调用递归函数时增加一个计数器，用来计算调用了多少次函数，最后输出Succ(n)的值和调用递归函数次数的值。(According to the requirement of topic, recursive function is used to calculate the value of Succ (n) according to the mathematical formula given by the title. A counter can be added each time the recursive function is called to calculate the number of functions called, and the value of the Succ (n) and the number of recursion functions to be invoked.)
