1502 - Can Make Arithmetic Progression From Sequence.<p>Easy</p>
<p>A sequence of numbers is called an <strong>arithmetic progression</strong> if the difference between any two consecutive elements is the same.</p>
<p>Given an array of numbers <code>arr</code>, return <code>true</code> <em>if the array can be rearranged to form an <strong>arithmetic progression</strong>. Otherwise, return</em> <code>false</code>.</p>
<p><strong>Example 1:</strong></p>
<p><strong>Input:</strong> arr = [3,5,1]</p>
<p><strong>Output:</strong> true</p>
<p><strong>Explanation:</strong> We can reorder the elements as [1,3,5] or [5,3,1] with differences 2 and -2 respectively, between each consecutive elements.</p>
<p><strong>Example 2:</strong></p>
<p><strong>Input:</strong> arr = [1,2,4]</p>
<p><strong>Output:</strong> false</p>
<p><strong>Explanation:</strong> There is no way to reorder the elements to obtain an arithmetic progression.</p>
<p><strong>Constraints:</strong></p>
<ul>
<li><code>2 <= arr.length <= 1000</code></li>
<li><code>-10<sup>6</sup> <= arr[i] <= 10<sup>6</sup></code></li>
</ul>
