4.2 Singly Linked List
A singly linked list is the simplest form of linked list, where each node points to the
next node in the sequence. The last node points to NULL, indicating the end of the list.
4.2.1 Creation of Nodes
Nodes in a singly linked list are created dynamically using pointers.
Example:
4.2.2 Traversal
Traversal involves visiting each node in the list sequentially, starting from the head.
Example:
4.2.3 Insertion Operations
Insertion can occur at the beginning, end, or a specific position. Each operation
requires adjusting pointers to maintain the list structure.
• At beginning: new node points to current head, then head is updated.
• At end: traverse to last node, update its pointer to new node.
• At position: traverse to desired location, adjust pointers accordingly.
4.2.4 Deletion Operations
Deletion involves removing a node and updating pointers to bypass it.
• At beginning: head is updated to point to the next node.
