What is the expected output of the program below?

void function(string str, int pos, int size);

int main()

{

string mystr = "Exam1";

function(mystr, 0, mystr.size());

return 0;

}

void function(string str, int pos, int size)

{

if(pos < size)

{

function(str, pos+1, size);

cout << str[pos];

}

}
