What will the code print when we call the function foo$()$ with the following parameters? If

necessary, assume that output arguments are copied back to parameters in the left$-$to$-$right

order. Please note the function foo is being called with different parameters at each of the

given question's below.

foo $(x,x,y)$ where all parameters are passed by value

foo $(x,z,y)$ where all parameters are passed by reference

foo $(z,y,x)$ where all parameters are passed by value$-$result

foo $(x,y,y)$ where all parameters are passed by reference
