For this Question: Given two strings A and B of equal length, We define an operation in which you can replace any substring of A with any substring of B such that the starting and ending points of the strings are the same. Your task is to count the number of unique strings you can transform A into by repeating the above operation any number of times.

<b>Note</b>:- Since the ans might be large print your answer as answer%(10<sup>9</sup> + 7)The first line of input contains a single integer N denoting the length of the string. The second line of the input contains a string A. The last line of input contains string B.

<b>Constraints:</b>
1 < = N < = 100000
 
<b>String will contain only lowercase english alphabets</b>Print the number of unique strings A can be transformed into modulus 10<sup>9</sup> + 7.Sample Input:-
5
newton
newton

Sample Output:-
1

Sample Input:-
3
abc
xyz

Sample Output:-
8

Explanation:-
unique strings:- { abc, xbc, xbz, xyc, xyz, ayc, ayz, abz}, I have written this Solution Code:

}
int ans=1;

ans=ans%MOD;
}
out(ans);
}
, In this Programming Language: C++, Now tell me if this Code is compilable or not?
