    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 <code>i<sup>th</sup></code> 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 &lt;= k &lt;= nums.length &lt;= 1000

    • <code>0 <= numsi<= 10<sup>5</sup></code>
