    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 minimum_absolute_difference(arr: &[i32]) -> i32 {
    //Time complexity: O(n*log(n))
    //Space complexity (ignoring input): O(n)
    let mut arr = arr.to_vec();
    arr.sort_unstable();
    let mut minimum_difference = (arr[0] - arr[1]).abs();
    for index in 2..arr.len() {
        let difference = (arr[index] - arr[index - 1]).abs();
        if minimum_difference > difference {
            minimum_difference = difference;
        };
    }
    minimum_difference
}

    #python 3 solution

from itertools import pairwise

def minimumAbsoluteDifference(arr):
    return min(b-a for a,b in pairwise(sorted(arr)))
