It can be initialized with a specific `size` and a default `val`. The `size` method returns the array's length. The `Value` method retrieves the element at a given `index`. `SetValue` allows modification of the array element at the given `index` with a new `val`, requiring a pointer `s` to a `Solver`. The class also contains a destructor, denoted by `~RevArray`.\n"]]
