Following is a binary search tree that was built based on its key values. But the key values are hidden in the figure and only labels (A,B,C, …) are shown.

 

(a) Suppose that the values are actually ten integer numbers 1, 3, 5, 8, 11, 13, 20, 24, 24, 29. Draw the binary search tree again with the numbers in the right place to keep binary search tree property.

(b) Draw the binary search tree after deleting the node A.
