Problem Statement

You are given strings s and t, consisting of lowercase English letters.
You will create a string s' by freely rearranging the characters in s.
You will also create a string t' by freely rearranging the characters in t.
Determine whether it is possible to satisfy s' < t' for the lexicographic order.

Notes

For a string a = a_1 a_2 ... a_N of length N and a string b = b_1 b_2 ... b_M of length M, we say a < b for the lexicographic order if either one of the following two conditions holds true:

N < M and a_1 = b_1, a_2 = b_2, ..., a_N = b_N.

There exists i (1 \leq i \leq N, M) such that a_1 = b_1, a_2 = b_2, ..., a_{i - 1} = b_{i - 1} and a_i < b_i. Here, letters are compared using alphabetical order.

For example, xy < xya and atcoder < atlas.

Constraints

The lengths of s and t are between 1 and 100 (inclusive).

s and t consists of lowercase English letters.

Input

Input is given from Standard Input in the following format:

s
t

Output

If it is possible to satisfy s' < t', print Yes; if it is not, print No.

Sample Input 1

yx
axy

Sample Output 1

Yes

We can, for example, rearrange yx into xy and axy into yxa. Then, xy < yxa.

Sample Input 2

ratcode
atlas

Sample Output 2

Yes

We can, for example, rearrange ratcode into acdeort and atlas into tslaa. Then, acdeort < tslaa.

Sample Input 3

cd
abc

Sample Output 3

No

No matter how we rearrange cd and abc, we cannot achieve our objective.

Sample Input 4

w
ww

Sample Output 4

Yes

Sample Input 5

zzz
zzz

Sample Output 5

No

import java.util.Scanner;

	public static void main(String[] args) {
		Scanner sc=new Scanner(System.in);
		String s=sc.next();
		String n=sc.next();
		char a[]=s.toCharArray();
		char b[]=n.toCharArray();
		a=sort(a);
		s=new String(a);
		b=sort(b);
		n=new String(b);
		if(s.compareTo(n)==1)
			System.out.print("Yes");
		else
			System.out.print("No");


	}
	public static char[] sort(char[] s) {
		for(int i=0;i<s.length-1;i++) {
			for(int j=i+1;j<s.length;j++) {
				if(s[i]>s[j]) {
					char h=s[i];
					s[i]=s[j];
					s[j]=h;
				}
			}
		}
		return  s;
