    Why it needs to trim()?

    If it doesn't trim() , it will not pass all the test even if they output the same thing

    Why?

    I would like to know

    import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        String s = scan.nextLine();
        scan.close();
        if (s.trim().length()==0 || s.trim().length()>400000){
        System.out.println(0);
        return;
        }
        s=s.trim();
        String regex = "[^(a-zA-Z)]+";
        String [] lista =s.split(regex);
        
       
        System.out.println(lista.length);
        
        
        for(String k:lista){
           System.out.println(k);
        }
        
        
        
    }
}
