2099 Find Subsequence of Length K With the Largest Sum
2099 Find Subsequence of Length K With the Largest Sum. This Java code finds the subsequence of length k from
the array nums that has the largest sum, while keeping the original order of elements.
How it works:
1. It uses a min-heap (priority queue) to keep track of the k largest numbers along with their indices.
2. It goes through all elements, adding them to the heap and removing the smallest if the heap size exceeds k.
3. After processing, the heap contains the k largest elements.
4. It extracts their indices, sorts them to maintain the original order, and then builds the result array using these indices.
5. Finally, it returns this subsequence.
