0020 , 0010 0043 0004 0018 0019 0021 0023 0060 Given the 2-3 trees shown above, what will be the root and leaves when the integer 20 is deleted from the tree? (Assume the root and leaves for the current tree would be represented as (Root(20), Leaves (4, (18,19), (21,23), 60).) Root(19), Leaves(4. (18,19), (21,23), 60) Root(19), Leaves(4, 18, (21,23), 60) Root(43), Leaves(4,18, (21,23), 60) Root(43), Leaves(4. (18,19), 21, 60)
