Thank You.


A binary tree is a tree in which each node has at most 2 children (hence the
term binary), usually denoted the left child and the right child, but there
is no restrictions as to what each node contains relative to other nodes.

A binary search tree is a binary tree that has the additional property that
all children to the left of a parent node contain values that are less than
the parent node, and all children to the right are greater than (where the
equal to nodes go can very from implementation to implementation).

So for example:
8
/ \
6 12
/ \ \
3 7 15

would be a binary search tree, as 3 is less than 6 (and thus to the left), 7
is greater than 6 (and thus to the right), 6 is less than 8 (and thus to 8's
left). Also note that there is nothing less than 12, but greater than 8, so
12 has no left child.

Hope this helps.

And BTW, if you think you are so

to four groups, (alt.comp.lang.learn.c-c++,
comp.lang.c++, comp.lang.java,
comp.lang.java.programmer),
please think again.

Thanks Adam that helps a lot.

Andrew I don't think I'm important I just wanted to someone to explain it to
me in a manner I can understand. I seen someone get flame for not telling
people they crosspost (SO I FIGURED I WAS DOING THE RIGHT THING BY LETTING
EVERYONE KNOW. SO WHEN PEOPLE GO TO OTHER GROUPS THEY WON"T ANSWER THE SAME
QUESTION. YOU CAN'T WIN WITH THIS GROUP) I did a google search I see
diagrams and didn't understand the concept. By actually speaking to someone
semi-live I can get a better understanding of it. I can't ask google a
specific question and get an answer. Google gives only what people put out
there and sometimes I can't understand that. So, I figure I come to the
newsgroup and ask the question. Isn't that's why this is here.

Why is that the C++ newsgroups have a bunch of people ready to attack than
help??? Andrew why don't you GOOGLE SEARCH THAT!!!!

Once again Thanks Adam I do understand it now.

no, but there are many flavours of tree structured search indexes.

Some of the more famous B-tree, B+tree, Red-Black tree (used in Java
Collections), binary tree, ISAM. Might check out Knuth for the
bestiary.

I should be more careful. It depends on who is using the term. Most
people throw that term around very loosely to describe any sort of
tree structure even when it is not binary!! e.g. an n-nary tree.

If your CS prof used the terms, he is making the distiction Andrew
mentioned.

First off, your question is off-topic in all of the newsgroups you
posted to (and comp.lang.java is not a valid newsgroup.) Your question
belongs in comp.programming (follow-ups set).

Normally, they are interchangeable terms, but if you want to be
pedantic, a binary search tree imposes a certain order on the nodes of
the tree while a normal binary tree just means that each node has no
more than two leaves.

You could have expressed that in your question.
<http://www.physci.org/codes/javafaq.jsp#specific>
..I seen someone get flame for not telling

Try basing your actions on actual information
in future. You do not seem terribly good at
this 'figuring'..

And please do not yell. I am not deaf.
..SO WHEN PEOPLE GO TO OTHER GROUPS THEY WON"T ANSWER THE SAME
QUESTION. YOU CAN'T WIN WITH THIS GROUP)
If they had any sense they would do the
same Google search I specified for you.

They would probably not be chasing up lazy
2 line questions that were cross-posted to
four groups.
..I did a google search I see
diagrams and didn't understand the concept.
Where did you express that in your smart question.?
<http://www.catb.org/~esr/faqs/smart-questions.html#before>

You _now_ claim to have done those things
(though not very convincingly), so let's
add a seventh..
7. Do not presume the audience is psychic
...By actually speaking to someone
semi-live I can get a better understanding of it. I can't ask google a
specific question and get an answer. Google gives only what people put out
there and sometimes I can't understand that. So, I figure I come to the
newsgroup and ask the question. Isn't that's why this is here.
To 'Ask a specific question and
get a (specific) answer'?

No. You are thinking of an _HelpLine_.
You pay for those, it's a service.

Newsgroups are communities of people who wish
to discuss subjects of common interest.
Why is that the C++ newsgroups have a bunch of people ready to attack than

(chuckles) I am glad you blamed the C++
folks. 'We' are horrible, no? ;-)

according to http://mindprod.com/jgloss/newsgroups.html (which was posted
by Roedy Green) a newsgroup is
newsgroups
Newsgroups are Internet forums, sort of like electronic bulletin boards,
where you can post questions.

Some people are frustrated because they imagine they are obligated to
read and answer nearly every post. It becomes infuriating when you
can't make any sense of the question.

You feel a sick feeling in your stomach, knowing this person is going
to be ignored, and he may never know why.

So you simultaneously feel pity and anger at having to deal with the
situation.

Sometimes the questioner is playing dumb blonde, and saying in effect,
poor widdle me. I am so stupid. Will you do my homework for me. The
only effort I am prepared to go to is to post the assignment. I have
no intention of even trying to understand the answer.

These people are infuriating. This a place to LEARN Java. If you
don't want to do that, GO AWAY. You are despised as a species of con
man. Their are so many more deserving people trying their best.
