    String[] sortedArray = Arrays.stream(s)
                             .filter(Objects::nonNull) 
                             .sorted((a, b) -> (new BigDecimal(b)).compareTo(new BigDecimal(a)))
                             .toArray(String[]::new);
        for(int i=0;i<n;i++)
        {
            s[i]=sortedArray[i];
        }

    public class Solution {

    public static void main(String[] args) {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */

    Arrays.sort(arr,(String a,String b)-> new BigDecimal(b).compareTo(new BigDecimal(a)));

    for(int i = 0; i < n; i++){

    Hello friends! I'm at this problem and try to figure out how ti solve it. i didn't pass 3 tests and I which what those are. The main problom for me is when i convert from string array to bigdecimals array some values suffering modifications like this : string array -> ".12" ==> to bigDecimals -> "0.12" and i don't want to happend. I've searched all internet but nothing can helped me. Do you have any advice? Thank you!

            for (int i=n; i>=0; i--) {
            for (int j=0; j<i-1; j++) {
                BigDecimal numA = new BigDecimal(s[j]);
                BigDecimal numB = new BigDecimal(s[j+1]);
                
                if (numA.compareTo(numB) == -1) {
                    String tmp = s[j];
                    
                    s[j] = s[j+1];
                    s[j+1] = tmp;
                }
            }
        }

        Arrays.sort(s, 0, n, new Comparator<String>() {

            BigDecimal B = new BigDecimal(b);
            return B.compareTo(A);

    });

    //Output
