    c++

    int maxMin(int k, vector<int> arr) {
    std::sort(arr.begin(), arr.end());
    int min, max, dif;
    dif = arr[arr.size() - 1] - arr[0];
    for (int i = 0; i <= arr.size() - k; i++) {
        min = arr[i];
        max = arr [i + k - 1];
        if (max - min <= dif) {
            dif = max - min;
        }
    }
    return dif;

    I am ashamed how much time it took me to finally understand whats going on. I guess it is a good practice on how to gather the useful observations on what the questions is actually about.

    These problems are poorly written.

    Rust best solution

    If you’re looking for solutions to the 3-month preparation kit in either Python or Rust, you can find them below: my solutions 

    fn max_min(k: i32, arr: &[i32]) -> i32 {
    //Time complexity: O(n*log(n))
    //Space complexity (ignoring input): O(n)
    let mut arr = arr.to_vec();
    let k = k as usize;
    arr.sort_unstable();
    let mut minimun_unfairness = arr[k - 1] - arr[0];
    for index in 1..(arr.len() - k + 1) {
        if minimun_unfairness > arr[k - 1 + index] - arr[index] {
            minimun_unfairness = arr[k - 1 + index] - arr[index];
        };
    }
    minimun_unfairness
}

    If you’re looking for solutions to the 3-month preparation kit in either Python or Rust, you can find them below: my solutions 

    def max_min(k, arr):
    #Time complexity: O(n*log(n))
    #Space complexity (ignoring input): O(1)
    arr.sort()
    minimum_unfairness = arr[k - 1] - arr[0]
    for index in range(1, len(arr) - k + 1):
        if minimum_unfairness > arr[index + k - 1] - arr[index]:
            minimum_unfairness = arr[index + k - 1] - arr[index]

    return minimum_unfairness
