{
int m;
printf("enter the number of lines :");
scanf("%d",&m);
for(int i=1;i<=(m/2+1);i++)
{
printf("\n");
if(i%2!=0)
logic1(i);
else
logic2();
}
for(i=1;i<=m/2;i++)
{
printf("\n");
if(i%2==0)
logic3();
else
logic4();
}
getch();
}
void logic1(int p)
{
a=(m/2+2)-p;
for(int i=a;i>=1;i--)
printf("%d",i);
}
void logic2();
{
a--;
for(int i=1;i<=a;i++)
printf("%d",i);
}
void logic3()
{
a++;
for(int i=a;i>=1;i++)
printf("%d",i);
}
void logic4()
{
a++;
for(int i=1;i<=a;i++)
printf("%d",i);
