題目描述 某人寫了n封信,同時為每一封信寫1個信封,共n個信封。如果把所有的信都裝錯了信封,問共有多少種?(這是組合數學中有名的錯位問題。著名數學家伯努利(Bernoulli)曾最先考慮此題。后來,歐拉對此題產生了興趣,稱此題是“組合理論的一個妙題”,獨立地解出了此題) 試編程求出完全裝錯情形的所有方式及其總量s。例如,輸入n=3,即有3封信需要裝入信封,完全裝錯的一種方式可以表示為312,表示第1封信裝入第3個信封,第2封信裝入第1個信封,第3封信裝入第2個信封。對于n=3,完全裝錯的方式共有2種,分別是312和231. 輸入 輸入一個正整數n(2<=n<=6) 輸出 輸出完全裝錯情形的所有方式以及裝錯方式的總量s (每行輸出5種方式,一行中的相鄰兩種方式之間用1個空格隔開。裝錯方式輸出時,從小到大排列,見輸出樣例)。 樣例輸入 4 樣例輸出 2143 2341 2413 3142 3412 3421 4123 4312 4321 s=9

This texts contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated treatment of both classical and modern control system methods. The text emphasizes design with discussions of problem formulation, design criteria, physical constraints, several design methods, and implementation of compensators.Discussions of topics not found in other texts--such as pole placement, model matching and robust tracking--add to the texts cutting-edge presentation. Students will appreciate the applications and discussions of practical aspects, including the leading problem in developing block diagrams, noise, disturbances, and plant perturbations. State feedback and state estimators are designed using state variable equations and transfer functions, offering a comparison of the two approaches. The incorporation of MATLAB throughout the text helps students to avoid time-consuming computation and concentrate on control system design and analysis
