/* Compile and Run
*
* To compile you will have to declare the location of the library with
* "-L." -> Libraries are located in the local directory
* and you will have to link it by using the "-l" attribute followed
* only by the name of the library without the prefix "lib" and the
* extension ".so":
*
* $gcc -o foo foo.c -L. -lmoo
*
* To RUN this "foo" program you will have to add the actual directory to
* the environment variable $LD_LIBRARY_PATH as follows:
*
* $ export LD_LIBRARY_PATH=.
*
* Check the content of the $LD_LIBRARY_PATH variable by typing:
*
* $ echo $LD_LIBRARY_PATH
*
* When done you are ready to run this program by calling it as usual:
*
* $./foo
*
* A call to "ldd foo" shows that the program is linked to the
* created "libmoo.so" library in the actual directory.

/*
Serialization is converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another computer environment.
Design an algorithm to serialize and deserialize a binary search tree. There is no restriction on how your serialization/deserialization algorithm should work. You need to ensure that a binary search tree can be serialized to a string, and this string can be deserialized to the original tree structure.
The encoded string should be as compact as possible.
Example 1:
Input: root = [2,1,3]
Output: [2,1,3]
Example 2:
Input: root = []
Output: []
Constraints:
The number of nodes in the tree is in the range [0, 10^4].
0 <= Node.val <= 10^4
The input tree is guaranteed to be a binary search tree.

/* GameProb.C
By Michael W. Maher
Ver 1.0 5/28/92
The following program is simulation of the game show problem. The problem
is as follows:
You are a contestant on a popular game show. At one point during the
show you are given the opportunity to select one of three doors.
Behind two of the doors is a sheep. Behind the other door is car.
You select a door and the show's host offers you the chance to trade
your door for the chance to choose one of the remaining doors. What
should you do?
The program was written in Microsoft C 5.0 for full ANSI C compatibility.
An ANSI C compiler should be able to compile the program. If you have any
questions or comments I would love to here from you. I can be reached at
the address above.

OpenMP-3.0 Example Codes Beta-v1.0
File : mem-consistency-openmp3x.c
Date : Aug 2011
Description : Simple example program to demonstrates the importance to
maintain the memory consistency.
In the example program , at Print 1, the value of x could be
either 2 or 5,depending on the timing of the threads, and the
implementation of the assignment to x. There are two reasons
that the value at Print 1 might not be 5. First,Print 1 might
be executed before the assignment to x is executed. Second, even
if Print 1 is executed after the assignment,the value 5 is not
guaranteed to be seen by thread 1 because a flush may not have
been executed by thread 0 since the assignment.
The barrier after Print 1 contains implicit flushes on all
thread as well as a thread synchronization, so the programmer
is guaranteed that the value 5 will be printed by both Print 2
and Print 3.
Input : None
Output : Value of the variable x
