Memory management in linked lists involves allocation and deallocation of nodes.
Dynamic memory allocation is used to create nodes in a linked list.
Memory leaks can occur if nodes are not properly deallocated.
Freed memory should be returned to the operating system using free() function.
Using a garbage collector can automate memory management in linked lists.
Arrays are fixed in size and contiguous in memory, while linked lists are dynamic and non-contiguous.
Arrays have constant time access to elements, while linked lists require traversal.
Arrays are better for random access, while linked lists are better for insertion and deletion.
Arrays use less memory overhead, while linked lists use more due to pointers.
Examples: array of integers vs linked list of nodes.
Examples: array
Explaining algorithms for various problem statements
For sorting: bubble sort, insertion sort, merge sort, quick sort
For searching: linear search, binary search
For graph traversal: breadth-first search, depth-first search
For dynamic programming: Fibonacci sequence, knapsack problem
For string manipulation: string reversal, palindrome check
