You must make sure that your code compiles successfully on a Linux operating system with g++ and the options -std=c++1z -Wconversion -Wall -Werror -Wextra -pedantic.

Test case specifications

These test cases are set to help you test your implementation to solve the convex hull problem. The test cases are in the following categories:

• Case 1-7: Normal test cases
• Case 8-10: Special test cases (such as colinear and duplicated points)

Please note that JOJ is not an efficient way to debug, and we recommend you to write your own test cases.
