Efficiently Solving the Two Sum Problem in Ruby | Leetcode Challenge 1

In this video, we tackle the well-known Two Sum problem from Leetcode using Ruby. This problem is a classic array and hash table problem which tests your understanding of data structures and how to use them effectively. We walk you through our solution, explaining the logic at every step so that you can grasp how to approach similar problems.

We utilize a hash map in our solution to efficiently find the two indices that sum up to a given target. By iterating through the array just once and keeping track of the complement of each number with respect to the target, we can quickly identify the correct pair. This gives our solution a time complexity of O(n), which is a significant improvement over a brute force approach.
