Find Subsequence of Length K With the Largest Sum | leetcode 2099

In this video, we solve “Find Subsequence of Length K With the Largest Sum” using a smart combination of sorting and hashing.

We first sort the array in descending order to find the top k elements, then use a hash map to preserve the original order while collecting those values into the final subsequence.

Great example of combining greedy logic with stable output constraints!
