|
|
|
|
<p><em>Return the array in the form</em> <code>[x<sub>1</sub>,y<sub>1</sub>,x<sub>2</sub>,y<sub>2</sub>,...,x<sub>n</sub>,y<sub>n</sub>]</code>.</p>

<p><strong>Example 1:</strong></p>
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
<strong>Input:</strong> nums = [2,5,1,3,4,7], n = 3
|
|
|
|
<strong>Output:</strong> [2,3,5,4,1,7]
|
|
|
|
<strong>Explanation:</strong> Since x<sub>1</sub>=2, x<sub>2</sub>=5, x<sub>3</sub>=1, y<sub>1</sub>=3, y<sub>2</sub>=4, y<sub>3</sub>=7 then the answer is [2,3,5,4,1,7].
