Answer 2

for(int i=0;i<5;i++){
int j=0
for(;j<i;j++) print(" ");
for(;j<9-2*i;j++)print("%d",j+1);
for(j=0;j<i;j++) print(" ");
}
for(int i=3;i>=0;i--){
int j=0
for(;j<i;j++) print(" ");
for(;j<9-2*i;j++)print("%d",j+1);
for(j=0;j<i;j++) print(" ");
}

Answer 3

Private Sub Command1_Click()
X = "123456789"
Y = Space(4)
For I = 1 To 5
Z = Mid(X, 6 - I, I * 2 - 1)
Print Right(Y, 5 - I) Z
Next
End Sub
