+<p>You are given an array of positive integers <code>price</code> where <code>price[i]</code> denotes the price of the <code>i<sup>th</sup></code> candy and a positive integer <code>k</code>.</p>
+
+<p>The store sells baskets of <code>k</code> <strong>distinct</strong> candies. The <strong>tastiness</strong> of a candy basket is the smallest absolute difference of the <strong>prices</strong> of any two candies in the basket.</p>
+
+<p>Return <em>the <strong>maximum</strong> tastiness of a candy basket.</em></p>
+

+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> price = [13,5,1,8,21,2], k = 3
+<strong>Output:</strong> 8
+<strong>Explanation:</strong> Choose the candies with the prices [13,5,21].
+The tastiness of the candy basket is: min(|13 - 5|, |13 - 21|, |5 - 21|) = min(8, 8, 16) = 8.
+It can be proven that 8 is the maximum tastiness that can be achieved.
+</pre>

+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> price = [1,3,1], k = 2
+<strong>Output:</strong> 2
+<strong>Explanation:</strong> Choose the candies with the prices [1,3].
+The tastiness of the candy basket is: min(|1 - 3|) = min(2) = 2.
+It can be proven that 2 is the maximum tastiness that can be achieved.

+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> price = [7,7,7,7], k = 2
+<strong>Output:</strong> 0
+<strong>Explanation:</strong> Choosing any two distinct candies from the candies we have will result in a tastiness of 0.
