摘要： Problem A - f91Time Limit: 1 secondBackgroundMcCarthy is a famous theorician of computer science. In his work, he defined a recursive function, called f91, that takes as input a positive integerNand returns a positive integer defined as follows:IfN ≤ 100, then f91(N) = f91(f91(N+11));IfN ≥ 101, then 阅读全文

摘要： The DecoderWrite a complete program that will correctly decode a set of characters into a valid message. Your program should read a given file of a simple coded set of characters and print the exact message that the characters contain. The code key for this simple coding is a one for one character s 阅读全文

摘要： The 3n+ 1 problemBackgroundProblems in Computer Science are often classified as belonging to a certain class of problems (e.g., NP, Unsolvable, Recursive). In this problem you will be analyzing a property of an algorithm whose classification is not known for all possible inputs.The ProblemConsider t 阅读全文
