Question $1$

Consider the following code:

$```$

public static int find$($int$[]$ list, int n$)\{$

int i $=0$;

int num $=$ list$[$i$]$;

while $($num $!=$ n$)\{$

num $=$ list$[$i$++]$;

$\}$

return $(($i $$ list.length$)?1$ : $-1)$;

$\}$

$```$

What does this method return when called from a main method:

int$[]$ list $=\backslash \{20,40,60,40\backslash \}$;

System.out.println$($find$($list$,40))$;

There is a syntax error; the return type is int, but the method is returning a boolean

The method returns $1$ because the first occurrence of the number $\backslash ($ n $\backslash )$ in the array list is at index $1$

The method returns $3$becausethe last occurrence of the numbernin the arraylistis at index $3$

The method returns $1$ becase the number $\backslash ($ n $\backslash )$ is present in the array list.
