2099. Find Subsequence of Length K With the Largest Sum | Leetcode Daily - Python

In this LeetCode tutorial, we're solving problem 2099: "Find Subsequence of Length K With the Largest Sum". This problem asks us to find the k numbers that give the biggest sum, but with a twist – we must maintain their original relative order!

We'll walk through a clear, step-by-step Python solution. The core trick involves pairing each number with its original index. This allows us to sort by value to identify the k largest numbers, and then sort again by index to restore the correct subsequence order. It's a fantastic technique for problems that require you to track both a value and its original position.
