for i := 1 to 12 do

for j := 5 to 10 do

for k := 15 downto 8 do

printf (i-j)*k

How many time is the print statement executed?

I thought it would be 12x5x7 but the answer key has 576?

Isn't the question ambiguous? For example "for i := 1 to 12" you don't know if another iteration will occur at 12 i.e. you don't know if it's i < 12 or i <= 12

Code:

```
do i=1,10
print*,i**2
end do
```
