/*
1. Initialization
Purpose: Initialize a new linked list and set the node count to zero.
Steps:
Allocate memory for a new linked list node.
Set the total_nodes field to zero.
Call the node initializer function.
*/
// Initialization
struct st_node *list = malloc(sizeof(struct st_node));
list->total_nodes = 0;
list = cs_node_initializer(list);


/*
2. Build the Node Chain
Purpose: Create a chain of nodes within a loop to prepare for adding pages.
Steps:
Initialize an index variable to zero.
Use a loop to add nodes to the chain.
Increment the index after adding each node.
Optionally, reset the current node pointer to the head of the list.
*/

}
index = 0;
list = cs_element_at(list, index); // Reset to the first node if needed.



/*
3. Add Pages to Nodes
Purpose: Populate each node in the linked list with data (pages).
Steps:
Access the current node.
Allocate memory for the page data.
Populate the page data.
Optionally, move to the next node within the loop.
*/
// Add Pages to Nodes

        list = cs_element_at(list, index);
}
index = 0;
list = cs_element_at(list, index); // Reset to the first node if needed.


/*
4. Combined Node Adding and Page Adding
Purpose: Simplify node and page creation within a loop by combining steps 2 and 3.
Steps:
Initialize an index variable to zero.
Determine the number of nodes and pages needed.
Use a loop to add nodes and populate pages.
Increment the index after each iteration.
*/
// Combined Node Adding and Page Adding
int index = 0;
int pages_needed = ...; // Define the total number of nodes and pages needed.
while (index < pages_needed) {
    // Add a new node
    list = cs_add(list);

    // Allocate memory for the page data
    struct st_number *number = malloc(sizeof(struct st_number));
    list->page = number;

    // Populate the page data if needed

    // Increment the index
    ++index;
}



/*
5. Free Pages from Nodes
Purpose: Properly release memory allocated for pages within the nodes.
Steps:
Access each node within a loop.
Free memory allocated for the page data.
Optionally, reset the current node pointer to the head of the list.
*/
// Free Pages from Nodes
index = 0;
while (index < list->total_nodes) {
    list = cs_element_at(list, index);
    free((struct st_number*)list->page); // Free page data
    ++index;
}
index = 0;
list = cs_element_at(list, index); // Reset to the first node if needed.


/*
6. Destroy the Node Chain
Purpose: Free memory associated with the entire linked list and its nodes.
Steps:
Use a function (e.g., cs_clear_nodes) to release memory for the linked list and nodes.
Optionally, free the main list structure itself.
*/
// Destroy the Node Chain
cs_clear_nodes(list); // Free memory for the entire linked list and its nodes
free(list); // Optionally free the main list structure
