Input Format

You are given two strings, a and b, separated by a new line. Each string will consist of lower case Latin characters ('a'-'z').

Output Format

In the first line print two space-separated integers, representing the length of a and b respectively.
In the second line print the string produced by concatenating a and b (a+b).
In the third line print two strings separated by a space, a' and b'. a' and b' are the same as a and b, respectively, except that their first characters are swapped.

int main() {
   string a,b;
   char a_tmp;
   getline(std::cin, a);
   getline(std::cin, b);
   cout << a.length() << " " << b.length() << endl;
   cout << a << b << endl;
   a_tmp = a[0];
   a[0] = b[0];
   b[0] = a_tmp;
   cout << a << " " << b << endl;
