What value will the program output when main is called? (Separate each output value with a single space).

Function Real double(Real x) Declare Real d Set d = x + x Return d End Function Function Real triple_double(Real x) Declare Real t Set t = double(x) + double(x) + double(x) Return t End Function Module main() Declare Real result Set result = double(triple_double(1.0)) Display result End Module
