Solution: Find Subsequence of Length K with the Largest Sum

Explore how to find a subsequence of length k with the largest sum from an integer array. Learn to use a min heap to track the top k elements efficiently while preserving their original order. Understand the algorithm's steps, including insertion, heap maintenance, and sorting by index to return the correct subsequence.

Statement

You are given an integer array nums and an integer k. Your task is to find a subsequenceA subsequence is an array derived from another array by deleting some or no elements while preserving the order of the remaining elements. of nums of length k that has the largest possible sum.

Constraints:

  • 11 \leq nums.length 1000\leq 1000

  • ...
