A Linked List is a linear data structure where elements (called nodes) are
stored in non-contiguous memory locations.
Each node contains:
Data – the actual value
Pointer (or Link) – address/reference to the next node

Why Use Linked List?
 Dynamic size (can grow or shrink during
execution)
 Easy insertion and deletion (especially in middle or
beginning)
 Better memory utilization compared to arrays

Structure of Linked List:
 Logical:
 Code: Struct Node{
int data;
Node *addr;
}
