The answer is B. The program prints:
9 2
This answer was checked by running the program for real.
Why?
// divides and throws away the remainder: each friend gets 9 sweets. % gives the remainder: 2 sweets left over.
Trace table
A trace table follows the program step by step. Here’s this one:
| sum | answer |
|---|---|
| 29 // 3 | 9 |
| 29 % 3 | 2 |
The code again
sweets = 29
friends = 3
print(sweets // friends, sweets % friends)Try it: change one number in the program and predict the new output before you run it.
