each time the while condition evaluates, the variable is decremented
and a recursive call to main is executed if it's true. when the
condition is finally false, the last function call ends without
printing, returning to the previous call on the stack, which does the
print then hits the end of the while loop. The while loop HAS to check
the condition again to know if it should loop or not, which results in
another decrement because the -- is inside the condition.
If the code was
while (i > 0) {
--i;
main();
printf("%d",i);
}
then the counter would only be decremented on a true while condition
check, resulting in all 0's being output (static becomes 0 on the
final recursive call, then is no longer decremented because all
further while condition checks are false and do not enter the while to
decrement it further).
