Data Structures and Algorithms The Complete Masterclass - Two Sum

The video tutorial covers the 2 Sum problem, a common interview question. It begins with an introduction to the problem and its constraints, followed by an example with a target of 9. The instructor explains a brute force approach using two loops, which has a complexity of O(n^2). Then, an optimized solution is presented using a dictionary to achieve O(n) complexity. The tutorial concludes with coding the solution and testing its efficiency.
