1 A) A binary search tree is to be built, the following numbers are input in the order given: 5, 15, 20, 25, 0, 11, 17, 9, 6, 18, 27 and 19. Draw the resulting tree. B) Next the numbers 5, 9 and 20 are deleted, from the tree resulting from the previous problem, in the given order, using the algorithm given in class, draw the tree after each deletion. 1 A) A binary search tree is to be built, the following numbers are input in the order given: 5, 15, 20, 25, 0, 11, 17, 9, 6, 18, 27 and 19.
