Write a method that takes an ArrayList and an int value and returns the first index at which value appears in the ArrayList.

If the value does not exist in the ArrayList, return $-1$

For example, if we had an ArrayList list with the values $[10,20,30,20]$:

search$($list$,20)$

Should return

$1$

Because $20$ first appears at index $1$ in the ArrayList.

If we had an ArrayList list with the values $[10,20,30,20]$:

search$($list$,40)$

Should return

$-1$

Because $40$ does not appear in the ArrayList.
