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

Solution in C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;

class test{
public static void Main(){
           char[] s = Console.ReadLine().ToCharArray();
            char[] t = Console.ReadLine().ToCharArray();
            Array.Sort(s);
            Array.Sort(t);

            int maxLoopCount = Math.Min(s.Length, t.Length);

            for (int i = 0; i < maxLoopCount; i++)
            {
                if (s[i] < t[i])
                {
                    Console.WriteLine("Yes");
                    return;
                } else if (s[i] > t[i])
                {
                    Console.WriteLine("No");
                    return;
                }
                else
                {
                    if (i != (maxLoopCount - 1))
                        continue;
                    else
                    {
                        Console.WriteLine((s.Length < t.Length) ? "Yes" : "No"); 
                    }
                }
            }
