DSA #12 | Arrays & Strings | Array Basics + Reverse Array/String

Описание: DSA Phase-2 Arrays and Strings tutorial focusing on Array Basics and Reverse operations.
In this video you will learn what an array is, how indexing and traversal work, and how to access and update array elements.

We will also cover how to reverse an array and reverse a string with step-by-step logic, dry run, and proper time and space complexity analysis. These are foundational problems for DSA and interviews.

Topics covered in this video:
--What is an array
--Indexing and traversal
--Access and update operations
--Reverse an array
--Reverse a string
--Step by step logic
--Dry run explanation
--Time complexity analysis
--Space complexity analysis

This video is useful for DSA beginners, students, freshers, and interview preparation.
