def get_elevation_maps(maps_file: TextI0) -> list[list[list[int]]]: IL I| || Given an open csv file <maps_file>, read the file according to the specification and return all the elevation maps stored within the file. IMPORTANT: the given argument to the function is an OPEN file <maps_file>, you will not need to open it again, and can begin performing standard file operations on it. The file will be structured as follows: The first line will contain one number, which will denote the number of elevation maps stored within this file. The next n lines will contain two numbers each, "r" and "c", which - are the number of rows and columns of each elevation map. The rest of the data will then be comprised of the elevation map data, which will follow one another in sequence, with no spaces in between. For an example, see "sample_data.csv". def write_elevation_maps(maps_file: TextI0, maps_list: list[list[list[int]]] ) -> None: Given an open csv file <maps_file> and a list of maps <maps_list>, write the maps back into the csv file according to the format specified in <get_elevation_maps>. That is, if the same file was then read from again by the <get_elevation_maps> function, it should return a list identical to <maps_list>. IMPORTANT: <maps_file> is an already open file, you can begin writing to it immediately. Furthermore, DO NOT close the file <maps_file> after you are finished writing the data in. IL I| || pass
