Ncurses是一个能提供功能键定义(快捷键),屏幕绘制以及基于文本终端的图形互动功能的动态库 您希望您的程序有一个彩色的界面吗?Ncurses是一个能提供基于文本终端窗口功能的动态库. Ncurses可以: 只要您喜欢,您可以使用整个屏幕 创建和管理一个窗口 使用8种不同的彩色 为您的程序提供鼠标支持 使用键盘上的功能键 Ncurses可以在任何遵循ANSI/POSIX标准的UNIX系统上运行,除此之外,它还可以从系统数据库中检测终端的属性, 并且自动进行调整,提供一个不受终端约束的接口.因此,Ncurses可以在不同的系统平台和不同的终端上工作的非常好. mc工具集就是一个用ncurses写的很好的例子,而且在终端上系统核心配置的界面同样是用ncurses编写的. 下面就是它们的截图: 哪里可以下载? Ncurses是基于GNU/Linux发展的,请访问 http://www.gnu.org/software/ncurses/ 以获得最新的更新版本或者其他详细信息以及相关链接 . 基础知识 为了能够使用ncurses库,您必须在您的源程序中将curses.h包括(include)进来,而且在编译的需要与它连接起来. 在gcc中您可以使用参数-lcurses进行编译. 在使用ncurses的时候,您有必要了解它的基础数据结构.它有一个WINDOW结构,从名字就很容易知道

Generate 10-digit number using a phone keypad

由 我的梦境 提交于 2019-12-17 22:19:24
问题 Given a phone keypad as shown below: 1 2 3 4 5 6 7 8 9 0 How many different 10-digit numbers can be formed starting from 1? The constraint is that the movement from 1 digit to the next is similar to the movement of the Knight in a chess game. For eg. if we are at 1 then the next digit can be either 6 or 8 if we are at 6 then the next digit can be 1, 7 or 0. Repetition of digits are allowed - 1616161616 is a valid number. Is there a polynomial time algorithm which solves this problem? The
