Problem $9\mathrm{.}1$: The following Arduino code is designed to turn on the onboard LED whenever a push button is pressed, but there are four errors that will prevent the code from working properly. On which lines are the four errors located? Select all that apply.

$1$: int pushButton $=2$;

$2$: int ledPin $=8$;

$3$:

$4$: void setup$()\{$

$5$: Serial.begin$(9600)$;

$6$: pinMode$($pushButton$,$ OUTPUT$)$;

$7$: pinMode$($ledPin$,$ INPUT$)$;

$8$: $\}$

$9$:

$10$: void loop$()\{$

$11$: int buttonState $=$ digitalRead$($pushButton$)$;

$12$: digitalwrite$($ledPin$,$buttonState$)$;

$13$: Serial.println$($buttonState$)$;

$14$: delay$(10)$;

$15$: $\}$
