实习时的一个课后小作业

#include    <stdio.h>
#define MIN(A,B) ((A<=B)?(A):(B))
    int
main ( )
{
    int i,j;

    for (i=1; i<=7; i++)
    {
        for (j=1; j<=3+MIN(i,8-i); j++)
        {
            if(MIN(i,8-i)+MIN(j,8-j)==5)
            {
                if(j<=4)
                    printf("%3d",i);
                else
                     printf("%3d",14-i);
            }
            else
            {
                if(j==4)
                    printf("%3d",14-2*i);
                else
                    printf(" ");
            }
        }
        printf("\n");
    }
    return 0;
}                /* ---------- end of function main ---------- */
/*
输出结果：


			1
		2	10	12
	3		8		11
4			6			10
	5		4		9
		6	2	8
			7
