## Find the K-Sum of an Array solution leetcode

Find the K-Sum of an Array solution leetcode – You are given an integer array `nums` and a positive integer `k`. You can choose any subsequence of the array and sum all of its elements together.

We define the K-Sum of the array as the `kth` largest subsequence sum that can be obtained (not necessarily distinct).

Return the K-Sum of the array.

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.

Note that the empty subsequence is considered to have a sum of `0`.

## Find the K-Sum of an Array solution leetcode

```Input: nums = [2,4,-2], k = 5
Output: 2
Explanation: All the possible subsequence sums that we can obtain are the following sorted in decreasing order:
- 6, 4, 4, 2, 2, 0, 0, -2.
The 5-Sum of the array is 2.
```

## Find the K-Sum of an Array solution leetcode

```Input: nums = [1,-2,3,4,-10,12], k = 16
Output: 10
Explanation: The 16-Sum of the array is 10.
```

## Find the K-Sum of an Array solution leetcode

• `n == nums.length`
• `1 <= n <= 105`
• `-109 <= nums[i] <= 109`
• `1 <= k <= min(2000, 2n)`
