<p>You are given an integer array <code>nums</code> and an integer <code>k</code>. Append <code>k</code> <strong>unique positive</strong> integers that do <strong>not</strong> appear in <code>nums</code> to <code>nums</code> such that the resulting total sum is <strong>minimum</strong>.</p>
|
|
|
|
<p>Return<em> the sum of the</em> <code>k</code> <em>integers appended to</em> <code>nums</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,4,25,10,25], k = 2
|
|
<strong>Output:</strong> 5
|
|
<strong>Explanation:</strong> The two unique positive integers that do not appear in nums which we append are 2 and 3.
|
|
The resulting sum of nums is 1 + 4 + 25 + 10 + 25 + 2 + 3 = 70, which is the minimum.
|
|
The sum of the two integers appended is 2 + 3 = 5, so we return 5.</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [5,6], k = 6
|
|
<strong>Output:</strong> 25
|
|
<strong>Explanation:</strong> The six unique positive integers that do not appear in nums which we append are 1, 2, 3, 4, 7, and 8.
|
|
The resulting sum of nums is 5 + 6 + 1 + 2 + 3 + 4 + 7 + 8 = 36, which is the minimum.
|
|
The sum of the six integers appended is 1 + 2 + 3 + 4 + 7 + 8 = 25, so we return 25.
