Solution: Find Subsequence of Length K with the Largest Sum

Explore how to identify the subsequence of length k that has the largest sum in an array. This lesson guides you through using a min heap to track the top k elements, then sorting by their original indices to maintain order. You will understand the algorithm's time and space complexities and how to implement this approach efficiently in Go.

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

  • ...
