Question: The minx(v) and max x (v) labels used in the two-dimensional range tree are not strictly needed. Describe an algorithm for performing a two-dimensional rangesearching

The minx(v) and max_x(v) labels used in the two-dimensional range tree are not strictly needed. Describe an algorithm for performing a two-dimensional rangesearching query in a two-dimensional range tree where each internal node of the primary structure only stores a key(v) label (which is the x-coordinate of its element). What is the running time of your method?
