Linked List Topics

Master essential linked list problems and patterns frequently asked in interviews.

•   01 Reverse Linked List Iterative and recursive reversal of a linked list
•   02 Detect Cycle in Linked List Floyd’s cycle detection algorithm (slow & fast pointers)
•   03 Merge Two Sorted Lists Classic merging problem using pointers
•   04 Palindrome Linked List Check palindrome using reverse second half technique
•   05 Intersection of Two Linked Lists Find the node where two lists intersect using pointer trick

WONDERING, HOW DOES IT COVER PATTERNS?
These problems cover the most important linked list patterns for interviews:

Reverse Linked List → Pointer manipulation, iterative & recursive techniques.
Detect Cycle → Floyd’s cycle detection (slow & fast pointers).
Merge Two Sorted Lists → Two-pointer merge, sorted order handling.
Palindrome Linked List → Middle finding, reversing, comparing halves.
Intersection of Two Linked Lists → Length difference trick, pointer redirection.

Together, they ensure you understand pointer manipulation, cycle detection, two-pointer merge, middle-finding, and intersection techniques in linked lists.
