Makefile Installing the make utility make-official documentation Learning Objectives At the end of this project, you are expected to be able to explain to anyone, without the help of Google:

General What are make, Makefiles When, why and how to use Makefiles What are rules and how to set and use them What are explicit and implicit rules What are the most common / useful rules What are variables and how to set and use them Copyright - Plagiarism You are tasked to come up with solutions for the tasks below yourself to meet with the above learning objectives. You will not be able to meet the objectives of this or any following project by copying and pasting someone else’s work. You are not allowed to publish any content of this project. Any form of plagiarism is strictly forbidden and will result in removal from the program. Requirements General Allowed editors: vi, vim, emacs OS: Ubuntu 20.04 LTS Version of gcc: 9.3.0 Version of make: GNU Make 4.2.1 All your files should end with a new line A README.md file, at the root of the folder of the project, is mandatory More Info Files In the following tasks, we are going to use these files. We want to compile these only.

5. Island Perimeter mandatory Technical interview preparation:

You are not allowed to google anything Whiteboard first Create a function def island_perimeter(grid): that returns the perimeter of the island described in grid:

grid is a list of list of integers: 0 represents a water zone 1 represents a land zone One cell is a square with side length 1 Grid cells are connected horizontally/vertically (not diagonally). Grid is rectangular, width and height don’t exceed 100 Grid is completely surrounded by water, and there is one island (or nothing). The island doesn’t have “lakes” (water inside that isn’t connected to the water around the island). Requirements:

First line contains #!/usr/bin/python3 You are not allowed to import any module Module and function must be documented guillaume@ubuntu:~/0x1C$ cat 5-main.py #!/usr/bin/python3 """ 5-main """ island_perimeter = import('5-island_perimeter').island_perimeter

if name == "main": grid = [ [0, 0, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0], [0, 1, 1, 1, 0, 0], [0, 0, 0, 0, 0, 0] ] print(island_perimeter(grid))
