数独是一种瑞士起源于第十八世纪后期的数学解释。
数独是一种源自18世纪末瑞士的数学智力拼图游戏。拼图是九宫格(即3格宽×3格高)的正方形状,每一格又细分为一个九宫格。在每一个小九宫格中,分别填上1至9的数字,让整个大九宫格每一列、每一行的数字都不重复。
数独的玩法逻辑简单,数字排列方式千变万化。不少教育者认为数独是锻炼脑筋的好方法。-Sudoku is a kind of Switzerland originated in late 18th century mathematical intelligence jigsaw puzzle. Puzzle is the squares (ie, 3 cells wide × 3 grid H) of square-shaped, each divided into a fine grid squares. Small squares in each of the respective fill in the figures 1-9, so that the whole big squares in each row, each row will not repeat the figures. The logic of playing Sudoku is simple, the arrangement of the ever-changing figures. Many educators think Sudoku is a good way to exercise their brains.

编写C程序,随机给出n*n的邻接矩阵,并打印输出邻接矩阵,以及有向图的边的个数,每个顶点的度,并判断该图中是否存在Euler回路:
(1)如果为n阶,则随机产生一个n*n的邻接矩阵;
(2)输出邻接矩阵,边的个数,每个顶点的度以及图中是否存在Euler回路。
这个题目涉及到了两个主要的知识点,一个是数据结构中的有向图的邻接矩阵的创建,还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)
