Algorithms: Searching, Sorting, Graph algorithms, Dynamic programming, etc.
Big O Notation:
Analysis of algorithm efficiency.
O(1), O(log n), O(n), O(n log n), O(n^2), etc.
Best case, worst case, and average case complexities.
Arrays and Strings:
Array operations: Access, insertion, deletion, and search.
String manipulation: Concatenation, substring, searching, and sorting.
Linked Lists:
Singly linked lists: Insertion, deletion, traversal, and searching.
