1984 - Minimum Difference Between Highest and Lowest of K Scores.

Easy

You are given a 0-indexed integer array nums, where nums[i] represents the score of the ith student. You are also given an integer k.

Pick the scores of any k students from the array so that the difference between the highest and the lowest of the k scores is minimized.

Return the minimum possible difference.

Example 1:

Input: nums = [90], k = 1

Output: 0

Explanation: There is one way to pick score(s) of one student:

• [90 ]. The difference between the highest and lowest score is 90 - 90 = 0.

The minimum possible difference is 0.

Example 2:

Input: nums = [9,4,1,7], k = 2

Output: 2

Explanation: There are six ways to pick score(s) of two students:

• [9 , 4 ,1,7]. The difference between the highest and lowest score is 9 - 4 = 5.

• [9 ,4, 1 ,7]. The difference between the highest and lowest score is 9 - 1 = 8.

• [9 ,4,1, 7 ]. The difference between the highest and lowest score is 9 - 7 = 2.

• [9, 4 , 1 ,7]. The difference between the highest and lowest score is 4 - 1 = 3.

• [9, 4 ,1, 7 ]. The difference between the highest and lowest score is 7 - 4 = 3.

• [9,4, 1 , 7 ]. The difference between the highest and lowest score is 7 - 1 = 6.

The minimum possible difference is 2.

Constraints:

• 1 <= k <= nums.length <= 1000
• 0 <= nums[i] <= 105
