Heap (Priority Queue)
You are given an integer array nums and an integer k. You want to find a subsequence of nums of length k that has the largest sum.
Return any such subsequence as an integer array of length k.
A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements.
Examples
Example 1
Input: nums = [2,1,3,3], k = 2
Output: [3,3]
Explanation:
The subsequence has the largest sum of 3 + 3 = 6.
Example 2
Input: nums = [-1,-2,3,4], k = 3
Output: [-1,3,4]
Explanation:
The subsequence has the largest sum of -1 + 3 + 4 = 6.
Example 3
Input: nums = [3,4,3,3], k = 2
Output: [3,4]
Explanation:
The subsequence has the largest sum of 3 + 4 = 7.
Another possible subsequence is [4, 3].
Constraints
1 <= nums.length <= 1000
-105 <= nums[i] <= 105
1 <= k <= nums.length
