You are given an array of positive integers price where price[i] denotes the price of the ith candy and a positive integer k.
The store sells baskets of k distinct candies. The tastiness of a candy basket is the smallest absolute difference of the prices of any two candies in the basket.
Return the maximum tastiness of a candy basket.
\n\n\n
Example 1:
\n\n\nInput: price = [13,5,1,8,21,2], k = 3\nOutput: 8\nExplanation: Choose the candies with the prices [13,5,21].\nThe tastiness of the candy basket is: min(|13 - 5|, |13 - 21|, |5 - 21|) = min(8, 8, 16) = 8.\nIt can be proven that 8 is the maximum tastiness that can be achieved.\n\n\n
Example 2:
\n\n\nInput: price = [1,3,1], k = 2\nOutput: 2\nExplanation: Choose the candies with the prices [1,3].\nThe tastiness of the candy basket is: min(|1 - 3|) = min(2) = 2.\nIt can be proven that 2 is the maximum tastiness that can be achieved.\n\n\n
Example 3:
\n\n\nInput: price = [7,7,7,7], k = 2\nOutput: 0\nExplanation: Choosing any two distinct candies from the candies we have will result in a tastiness of 0.\n\n\n
