The answer is A. The program prints:
1 2 Beep 4 5 Beep 7 8 Beep 10
Why?
Every number that divides exactly by 3 (remainder 0) is replaced by ‘Beep’. All the others are printed as they are.
Trace table
A trace table follows the program step by step. Here’s this one:
| number | number % 3 | printed |
|---|---|---|
| 1 | 1 | 1 |
| 2 | 2 | 2 |
| 3 | 0 | Beep |
| 4 | 1 | 4 |
| 5 | 2 | 5 |
| 6 | 0 | Beep |
| 7 | 1 | 7 |
| 8 | 2 | 8 |
| 9 | 0 | Beep |
| 10 | 1 | 10 |
The code again
for number in range(1, 11):
if number % 3 == 0:
print("Beep")
else:
print(number)Try it: change one number in the program and predict the new output before you run it.
