COMP9021 Principles of Programming
Term 2, 2024
Coding Quiz 3
Worth 4 marks and due Week 5 Thursday @ 9pm
Description
You are provided with a stub in which you need to insert your code where indicated without doing any
changes to the existing code to complete the task. Although it is not needed for this quiz, you may import
any module that is already installed in Ed if you wish.
The current code prompts the user for a positive integer.
This positive integer, when written in base 3, its consecutive digits read from left to right represent the
directions to take, with:
0 meaning going South (S),
1 meaning going South West (SW), and
2 meaning going South East (SE).
Your task is to print out:
1. the representation of the integer in base 3,
2. the corresponding sequence of directions to take as arrows, and
3. the sequence of arrows again, but nicely displayed.
The leftmost arrow is printed out with no space to the left.
The arrows are the Unicode characters of code point:
Use, for instance, print('\u2b07') to display ?.
The provided stub and the outputs of the sample test cases explain the task to be performed.

Marking
Representation of the integer in base 3 1.25 marks
Corresponding sequence of arrows 1.25 marks
Sequence of arrows nicely displayed 1.50 marks
