Mastering the "Sorted Subsequence of Size 3"...

Finding a sorted subsequence of a specific size is a classic algorithmic challenge that tests your ability to optimize array traversals. The problem asks us to find three elements in an array such that arr[i] < arr[j] < arr[k] and their indices satisfy i < j < k. If you are preparing for coding interviews or just sharpening your problem-solving skills, this problem is a fantastic way to transition from brute-force thinking to highly optimized logic. In this post, we will explore two distinct app
