The answer is C. The program prints:
48
Why?
The loop remembers the biggest number it has seen so far, and replaces it whenever it finds a bigger one. This is how computers find the maximum.
Trace table
A trace table follows the program step by step. Here’s this one:
| n | n > biggest? | biggest |
|---|---|---|
| 42 | yes | 42 |
| 14 | no | 42 |
| 48 | yes | 48 |
| 5 | no | 48 |
| 43 | no | 48 |
The code again
numbers = [42, 14, 48, 5, 43]
biggest = 0
for n in numbers:
if n > biggest:
biggest = n
print(biggest)Try it: change one number in the program and predict the new output before you run it.
