What is the output of the following code? struct someType { int a; int b; }; void f1(someType &s) { s.a = 1; s.b = 2; } someType f2(someType s) { someType t; t = s; s.a = 3; return t; } int main() { someType s1, s2; f1(s1); s2 = f2(s1); cout << s1.a << '-' << s1.b << '-' << s2.a << '-' << s2.b << '-' << endl; return 0; }

What should be placed in the blank to finish the code?
