Topic Link: http://acm.hdu.edu.cn/showproblem.php?pid=5399;Test instructionsGive you m function f1,f2,?, fm:{1,2,?, n}→{1,2,?, N} (that is, all x∈{1,2,?, n}, corresponding f (x) ∈{1,2,?, n}), known as a part of the function value, ask you how many different combinations make all I (1≤i≤n) , Meet F1 (F2 (FM (i))) =iFor the set of functions F1,F2,?, FM and G1,G2,?, GM, when and only if there is an I (1≤i≤m), J (1≤j≤n), Fi (J) ≠gi (j), such a combination is considered different. Where input-1 means

classic problems and algorithms such as the seven bridges in gonisburg, the juvenile Gaussian summation method, the Tower of Hanoi, And the Fibonacci series. Guides readers to deeply understand the mathematical methods and ideas in programming.The division of labor between programmers and computers is also discussed in mathematics of programmers. After reading this book, you will have a deeper understandin

suffix form, assuming that the given syntax guidance is defined as follows (where the left is a grammar-producing type, and the right is an additional semantic rule that defines the semantic rules from infix to postfix conversions): The grammar guidance definition corresponding to the syntax guidance translation plan is as follows: due to the existence of a left recursion problem (caused by non-terminator expr ) in the translation plan above, adjustments are required to eliminate left recu

Today, I saw someone complaining on the Internet that I didn't sell this set of books in China, so I found that there was a set of books that suit my taste :) Do you like mathematics? Do you like games? If the answer is yes, I believe you will not miss this set of classics. This set of books is the second version of the authoritative work of mathematics games (the first version is already in 1980s). After reading it, you will find that you have played many chess games before, puzzle games,
