 # Module Topic: Algorithms and Data Structures (Part 1)
 
+## Module Overview
+
+This module serves as an introduction to the fundamental concepts of algorithms and data structures in programming. It aims to provide students with a foundational understanding of algorithm efficiency metrics, such as Big O notation, and the use of various basic data structures. The module covers arrays, matrices, stacks, queues, pointers, linked lists, and binary search trees (BSTs). Through this module, students will not only learn the theoretical aspects but also apply these concepts in solving typical problems.
