<p>In the universe Earth C-137, Rick discovered a special form of magnetic force between two balls if they are put in his new invented basket. Rick has <code>n</code> empty baskets, the <code>i<sup>th</sup></code> basket is at <code>position[i]</code>, Morty has <code>m</code> balls and needs to distribute the balls into the baskets such that the <strong>minimum magnetic force</strong> between any two balls is <strong>maximum</strong>.</p>
|
|
|
|
<p>Rick stated that magnetic force between two different balls at positions <code>x</code> and <code>y</code> is <code>|x - y|</code>.</p>
|
|
|
|
<p>Given the integer array <code>position</code> and the integer <code>m</code>. Return <em>the required force</em>.</p>

<pre>
|
|
<strong>Input:</strong> position = [1,2,3,4,7], m = 3
|
|
<strong>Output:</strong> 3
|
|
<strong>Explanation:</strong> Distributing the 3 balls into baskets 1, 4 and 7 will make the magnetic force between ball pairs [3, 3, 6]. The minimum magnetic force is 3. We cannot achieve a larger minimum magnetic force than 3.

|
|
<strong>Explanation:</strong> We can use baskets 1 and 1000000000.
