A singly linked list is a data structure in which elements, called nodes, are connected in a linear sequence. Each node in a singly linked list contains two components:
Data: The actual information or value stored in the node.
Next Pointer: A reference or link to the next node in the sequence.
The last node in the list typically has a null reference as its "next" pointer, indicating the end of the list. Singly linked lists allow for efficient insertion and deletion of elements at the beginning or end of the list. However, accessing elements at arbitrary positions may require traversing the list from the beginning, which can be less efficient compared to other data structures like arrays
