Rotate 2D Matrix

Introduction

This project aims to implement a solution for rotating an n x n 2D matrix 90 degrees clockwise in Python. The provided script, main_0.py, tests the functionality of the rotate_2d_matrix function.

Requirements

General

• Allowed Editors: vi, vim, emacs
• Interpretation/Compilation: Ubuntu 20.04 LTS using python3 (version 3.8.10)
• File Endings: All files should end with a new line
• First Line: The first line of all files should be exactly #!/usr/bin/python3
• README File: A README.md file at the root of the project folder is mandatory
• Code Style: Your code should follow the pycodestyle style (version 2.8.0)
• Module Import: You are not allowed to import any module
• Documentation: All modules and functions must be documented
• Executable Files: All files must be executable

Tasks

Rotate 2D Matrix

• Task: Given an n x n 2D matrix, rotate it 90 degrees clockwise.
• Prototype: def rotate_2d_matrix(matrix):
• Output: Do not return anything. The matrix must be edited in-place.
• Assumptions: You can assume the matrix will have 2 dimensions and will not be empty.

Test Script

The provided test script, main_0.py, can be used to validate the correctness of the rotate_2d_matrix function. Simply execute the script, and it will rotate the sample matrix and print the result.

./main_0.py
