prim(n, 2);
}
6、寻找迷宫的一条出路，o：通路； X：障碍。（大家经常谈到的一个小算法题）
#define MAX_SIZE 8
int H[4] = {0, 1, 0, -1};
int V[4] = {-1, 0, 1, 0};
char Maze[MAX_SIZE][MAX_SIZE] = {{'X','X','X','X','X','X','X','X'},
{'o','o','o','o','o','X','X','X'},
{'X','o','X','X','o','o','o','X'},
{'X','o','X','X','o','X','X','o'},
{'X','o','X','X','X','X','X','X'},
{'X','o','X','X','o','o','o','X'},
{'X','o','o','o','o','X','o','o'},
{'X','X','X','X','X','X','X','X'}};
void FindPath(int X, int Y) {
if(X == MAX_SIZE || Y == MAX_SIZE) {
for(int i = 0; i < MAX_SIZE; i++)
for(int j = 0; j < MAX_SIZE; j++)
printf(\'\\n');
}else for(int k = 0; k < 4; k++)
if(X >= 0 && Y >= 0 && Y < MAX_SIZE && X < MAX_SIZE && 'o' == Maze[X][Y]) {
Maze[X][Y] = ' ';
FindPath(X+V[k], Y+H[k]);
Maze[X][Y] ='o';
}
}
int main(int argc, char* argv[]) {
FindPath(1,0);
}
7、随机分配座位，共50个学生，使学号相邻的同学座位不能相邻(早些时候用C#写的，没有用C改写）。
static void Main(string[] args)
{
int Tmp = 0, Count = 50;
int[] Seats = new int[Count];
bool[] Students = new bool[Count];
System.Random RandStudent=new System.Random();
Students[Seats[0]=RandStudent.Next(0,Count)]=true;
for(int i = 1; i < Count; ) {
Tmp=(int)RandStudent.Next(0,Count);
if((!Students[Tmp])&&(Seats[i-1]-Tmp!=1) && (Seats[i-1] - Tmp) != -1) {
Seats[i++] = Tmp;
Students[Tmp] = true;
}
}
foreach(int Student in Seats)
System.Console.Write(Student + \
System.Console.Read();
}
