What is wrong in my code

#1

public static void main(String[] args) {
Scanner sc= new Scanner(System.in);
int n =sc.nextInt();
for(int i=0;i<n;i++) {
String s=sc.next();
fun("", 0, s.length(), s);

	}

	
}
public static void fun(String t ,int i,int n,String s) {
	if(i==n) {
		System.out.println(t);
		return;
	}
	else {
		fun(t, i+1, n, s);
		t=t+s.charAt(i);
		fun(t, i+1, n, s);
	}
	
}

}

@deepgarg46 You have to print the subsequences in Lexicographical order. So you have two ways :
Either Sort your string before getting all subsequence or you can store all your subsequences in array and then sort the array and print it. The latter way is preferred.

i have to write a separate fun for comparation?

@deepgarg46 You can use anything you want. You just need to sort the array by any method.
