Binary Search Tree II
Write a program which performs the following operations to a binary search tree T by adding the find operation to A: Binary Search Tree I.
insert k: Insert a node containing k as key into T.
find k: Report whether T has a node containing k.
print: Print the keys of the binary search tree by inorder tree walk and preorder tree walk respectively.
For each find k operation, print "yes" if T has a node containing k, "no" if not.
In addition, for each print operation, print a list of keys obtained by inorder tree walk and preorder tree walk in a line respectively. Put a space character before each key.
