Data Structures and Algorithms The Complete Masterclass - Reverse Strings

The video tutorial discusses the problem of reversing a string given as an array of characters, with the constraint of not using extra space. It explores initial solutions using Python's built-in methods and their limitations due to space complexity constraints. The tutorial then introduces the two-pointer technique as an efficient solution, explaining how to implement it in Python. The video concludes with an analysis of the time and space complexity of the solution, emphasizing the importance of the two-pointer concept in algorithm design.
