What is the output of the following code?

class A:

def dots $ini{t}_{\text{s}\text{e}\text{l}\text{f}}$:

self.$x=1$

self.${?}_y=1$

def getY $($self$)$:

return self. $y$

$a=A()$

$a*y_{?}=45$

$pr{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(a*getx())$

The program has an error because y is private and cannot be

accessed outside of the class.

The program has an error because $x$ is private and cannot be accessed outside of the class

The program runs fine and prints $1.$
