• updated binary-tree.c to include a node typedef, a list typedef and some methods
• these methods include:

// function to print a linked list l starting at the first node
void printList(list l){
  node n = l->first;    // n = first node
  while(n != NULL){
    printf(" %d ", n->data);
    n = n->next;
  };
};

// function to return a list struct with first and last node initiated as NULL and length 0
list createList(){
  list new_list = (list)malloc(sizeof(struct node_list));
  new_list->length = 0;
  new_list->first = NULL;
  new_list->last = NULL;
  return new_list;
};

// function to push a given node n into the end of a given list l
void push(list l, node n){
  if(l->length == 0){
    l->first = n;
    l->last = n;
    l->length = 1;
  } else {
    l->last->next = n;
    l->last = n;
    l->length++;
  }
}

// insert a new node n, with data - int data- after node prev
void insertAfter(node prev, int data){
  node n = createNode(data);
  n->next = prev->next;
  prev->next = n;
}

• Implemented a basic binary tree that needs some refactoring
• created a function that recursively traverses the tree and prints the data in the nodes from left to right
• most of the code for this i found here: https://www.geeksforgeeks.org/tree-traversals-inorder-preorder-and-postorder/
• Tried to make a function that would take a linked list as an input and create a binary tree but didn't get that far and left the start of it in comments
