Pointer Wars 2025: Linked List Edition Week 1

The task for this week is to implement all of the functions declared in linked_list.h and have them pass all of the functional tests in the provided functional test suite. Once that is complete send us an email (pointerwars2025@gmail.com). For participants in the free tier: we'll let you know about next steps for week 2.

For paying participants: Either attach your code to the email or point us at your Github. Assuming your code passes valgrind and functional tests we will send you your code feedback and performance results.

In terms of memory allocation and deallocation, your library depends on user-specified malloc() and free() functions, registered via the linked_list::register_malloc() and linked_listLLregister_free() functions. See the malloc_fptr and free_fptr function pointer variables in linked_list.cc, which you can use in your implementation of your linked list. One of the reasons for this is code like instrumented_malloc() in linked_list_test_program.cc. Another reason is to allow you to specify to me whether you'd like to use a memory allocation library other than libc's implementation of malloc()/free().
