<p>You are given an array <code>nums</code> consisting of positive integers.</p>
|
|
|
|
<p>Starting with <code>score = 0</code>, apply the following algorithm:</p>
|
|
|
|
<ul>
|
|
<li>Choose the smallest integer of the array that is not marked. If there is a tie, choose the one with the smallest index.</li>
|
|
<li>Add the value of the chosen integer to <code>score</code>.</li>
|
|
<li>Mark <strong>the chosen element and its two adjacent elements if they exist</strong>.</li>
|
|
<li>Repeat until all the array elements are marked.</li>
|
|
</ul>
|
|
|
|
<p>Return <em>the score you get after applying the above algorithm</em>.</p>

<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [2,1,3,4,5,2]
|
|
<strong>Output:</strong> 7
|
|
<strong>Explanation:</strong> We mark the elements as follows:
|
|
- 1 is the smallest unmarked element, so we mark it and its two adjacent elements: [<u>2</u>,<u>1</u>,<u>3</u>,4,5,2].
|
|
- 2 is the smallest unmarked element, so we mark it and its left adjacent element: [<u>2</u>,<u>1</u>,<u>3</u>,4,<u>5</u>,<u>2</u>].
|
|
- 4 is the only remaining unmarked element, so we mark it: [<u>2</u>,<u>1</u>,<u>3</u>,<u>4</u>,<u>5</u>,<u>2</u>].
|
|
Our score is 1 + 2 + 4 = 7.

|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [2,3,5,1,3,2]
|
|
<strong>Output:</strong> 5
|
|
<strong>Explanation:</strong> We mark the elements as follows:
|
|
- 1 is the smallest unmarked element, so we mark it and its two adjacent elements: [2,3,<u>5</u>,<u>1</u>,<u>3</u>,2].
|
|
- 2 is the smallest unmarked element, since there are two of them, we choose the left-most one, so we mark the one at index 0 and its right adjacent element: [<u>2</u>,<u>3</u>,<u>5</u>,<u>1</u>,<u>3</u>,2].
|
|
- 2 is the only remaining unmarked element, so we mark it: [<u>2</u>,<u>3</u>,<u>5</u>,<u>1</u>,<u>3</u>,<u>2</u>].
|
|
Our score is 1 + 2 + 2 = 5.
