    // worked

    import java.util.Arrays; import java.util.Scanner;

    public class Solution {

    public static void main(String[] args) {

    Scanner in = new Scanner(System.in);
String s = in.nextLine();

String[] tokens = s.split("[ !,?._'@]+");
tokens = Arrays.stream(tokens).filter(token -> !token.isBlank()).toArray(String[]::new);

System.out.println(tokens.length);
for (String token : tokens) System.out.println(token);

    } }

    // Write your code here.
        String trimmed=s.trim();
        String[] tokens = trimmed.split("[ !,?._'@]+");
        int tokenCount=0;
        for(String token: tokens){
            if(!token.isEmpty()){
                tokenCount++;
            }
        }
        System.out.println(tokenCount);
        for (String token : tokens) {
            System.out.println(token);
        }

    can anybody tell me why trim() is required at all? the regex can handle the leading and trailing spaces but still when i am not using trim(), my code fails on a few test cases even after producing the exact same output as required for those cases! kinda confused
