摘要： BackgroundMcCarthy is a famous theorician of computer science. In his work, he defined a recursive function, called f91, that takes as input a positive integer N and returns a positive integer defined as follows:If N ≤ 100, then f91(N) = f91(f91(N+11));If N ≥ 101, then f91(N) = N-10.The ProblemWrite 阅读全文
