Problem Name: Longest Arithmetic Subsequence of Given Difference (1218)
Problem Difficulty: Medium
Language Used: C++

Welcome to my YouTube channel, where I provide comprehensive solutions to LeetCode coding challenges! In this video, I tackle the "Longest Arithmetic Subsequence of Given Difference" problem, a medium-difficulty challenge. Join me as I walk you through a step-by-step C++ solution to this intriguing problem, utilizing hashing with a hashtable.

LeetCode Problem: Longest Arithmetic Subsequence of Given Difference
The "Longest Arithmetic Subsequence of Given Difference" problem requires us to find the length of the longest subsequence in an array, where the difference between consecutive elements remains constant. In this video, I showcase how to efficiently solve this problem using hashing with a hashtable in C++.

Throughout the video, I explain the problem in detail, discussing the underlying concepts and reasoning behind the solution approach. I demonstrate how to implement a hashtable to keep track of the lengths of arithmetic subsequences and efficiently update them as we iterate through the array. By following along with my explanations and code implementation, you'll gain a deeper understanding of how to apply hashing techniques to solve similar problems.
