$(60$ points$)$ Suppose that we have two programming languages called A and $B$ which are Object Oriented and have a Java$-$like syntax. These languages have the following semantic differences:

In A multiplication has higher precedence than divison, in B divison has higher precedence

In A the assignment operator has copy semantics but in B it has reference semantics.

Functions are first class values in A but not in $B.$

In A$,$ function parameters are pass by value but in B they are pass by reference.

A allows flexible arrays but B only allows static arrays

Associate each code snippet below with a concept shown in bold above. Then, if there are print statements inside the code give the output for both languages. Otherwise, specify in which language the code will be valid or invalid.
