Understanding Linked Lists: A Solution to Array Limitations
- Arrays are versatile and efficient data structures, but come with limitations like fixed size and sequential memory allocation.
- Linked lists are dynamic data structures that store data in non-contiguous memory locations, allowing flexibility in size and efficient memory utilization.
- Linked lists eliminate the need for contiguous memory allocation making it resilient to fragmentation.
- Linked lists can dynamically grow or shrink during runtime without the need to pre-allocate or reallocate memory.
- Adding or removing elements from linked lists is faster than in arrays, especially in the middle of the structure.
- Singly linked, doubly linked, and circular linked lists are three types of linked lists.
- Creating a linked list in C++ involves defining a node class and implementing the data and next pointer.
- Memory for linked list nodes is allocated dynamically and needs to be deallocated using delete to avoid memory leaks.
- Linked lists require more memory overhead than arrays, and slower access times since traversal is required.
- Linked lists are a powerful alternative to arrays when dynamic size and efficient insertions or deletions are required.
