Minimum Difference Between Highest and Lowest of K Scores
We need to 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.
Understanding the Problem
We are given an array of integers representing the scores of students. We want to pick k scores and minimize the difference between the highest and lowest of those k scores.
Solution Approach
Sort the Array: To easily find the minimum difference between k elements, first, sort the array.
Slide a Window of Size k: Now, slide a window of size k through the sorted array and calculate the difference between the largest and smallest elements in that window. Keep track of the minimum difference found so far.
Return the Result: Return the minimum difference.
The code:


Key Takeaways
 Sorting the array simplifies the process of finding the minimum difference between k elements.
 By sliding a window of size k through the sorted array, we can easily calculate the difference between the largest and smallest elements in that window.
 The minimum difference among all such windows is our final result.
The given code meets the constraints and efficiently calculates the desired minimum difference.
