Suppose the subprogram header is changed to the following:

Subprogram Sub(Integer Num1 As Ref,Integer Num2)

If code corresponding to the new pseudocode is run, what is the output now?

Main Declare X As Integer, Y As Integer Set X = 1 Set Y = 2 Call Sub(X, Y) Write X Write Y End Program Subprogram Sub(Integer Numl, Integer Num2 As Ref) Declare X As Integer Set Numl = 3 %3! Set Num2 = 4 %3! Set X = 5 Write X End Subprogram
