 * <strong>Author a method</strong> named `array_equals` that accepts two integer arrays as input parameters. The method should return `true` if the arrays contain the same count of elements, the element values in the array are the same and they are in the same exact order. Otherwise, the method should return `false`.
 
 **Note:** Do not use Array class methods for comparing the whole array at once. You may use array indexing to retrieve one element at a time, you may compare individual elements with each other and you may retrieve the length of an array. Do not use any other Ruby provided functions.
