contains

Given an array, recursively determine whether the specified value appears in the array. Note: You should solve this recursively (no loops). You will need a recursive helper method that takes an array, a value, and an index as parameters.

contains([1, 2, 3], 1) → true
contains([5], 6) → false
contains([0, 7], 7) → true
