Question

Answer as correct or incorrect

This question has to do with an array based list datastructure, like the one we studied in class. In this representation, a list is represented with an array, and an integer. Interestingly, one list (from a logical/abstract standpoint) may be correctly represented by many different array and integer combinations. Which of the following arrays and integers can represent the following list: [cat, dog, mouse] (Note, I'll format these as array, integer. So each array will be formatted as {a, b, c, d, e, f,g} and will be followed by a valid for the integer variable. [Select ] {cat, dog, mouse}, 3 [Select] {cat, dog, mouse, null}, 2 [Select] {cat, dog, mouse, null}, 3 [Select] {cat, dog, moues, null}, 4
