class ABC :

$x=56$

def$\_\_$init$\_($self$,$x$)$:

self.i $=$self.$x$

$i=34$

$x=78$

$a=$ABC$(12)$

Using this code, answer the all of the questions:

What is the initial value of a$.$i$?$

Does it change after it is initially set, and if so$,$ what is its final value?

What is the value of ABC.$x?$
