How Can I Search A Word in A Binary Search Tree? 
You'll have to walk the whole tree since you're not searching by id,
but you seem to realize that already. To walk the tree in order using
recursion, recursively call your function on the left subtree, process
the current node, then recursively call the function on the right
subtree (checking for NULL appropriately). Example:
void listWord(node *tree, char *word)
{
if (tree) {
/* I

Binary search on list 
List has a binary search method but since binary search is so easy to
implement and since the IComparator you would need to define is so
complex due to the range thing I suggest you implement the binary
search method
Something like this (NOT TESTED!)
public static IPRange BinarySearch(List<IPRange> source, int
intIp)
{
int startIndex = 0;
int endIndex = source.Count;
while (end

Recursive Binary Search in C++ 
There are two problems with your code:
In your binarySearch() method, you are comparing values, not keys.
This may be what you wanted but you don't have value 2 stored in your
list (see point 2).
You insertAfter() method inserts chars that when printed give
0,1,2,3,4,5,6 but in fact their int values (based on which you make
the comparison) are the following: 48,49,50,51,52,53,54.

C++: Binary search tree end() iterator 
The end iterator doesn't necessarily have to be one past the last
element (that makes sense for vectors, but less so for trees eg.). It
has to just be an iterator that can clearly be identified as not a
valid iterator used for indicating that the end of the data structure
is reached.
Practically, this can be done in several ways, depending on how your
iterator refers to what it's pointing to. If

how to add a node in a binary search tree 
So 2 things
NoneType is capitalized: None (all if's you do in create_node)
Python string comparison is casesensitive, so when you check for
pointer["number"] value you are not really checking the one you set in
the create_node method, which it's key is "Number"(capital "N"), being
the reason it throws KeyError. Same for "right" and "left".
