difference between Full Binary Tree and Complete Binary Tree

topics	Full Binary Tree	Complete Binary Tree
1.node assemble	it's a regular binary tree with no odd number of leaves.	Every node or level of a tree is completely filled exception can happen only in the last level.
2.last node	Last and each node must have either 0 (zero) or 2 (two) children.	Children on the last level node must start from the left most position with no spot left unoccupied in between any tow form the left counting.
3.application	n/a	Some specific data structure type (i.e. Heaps) need to be in Complete Binary Tree shape, when they need not to be a Full Binary Tree.
4.formula	If one can find any of  Number of Total Nodes or  Number of Laves or  Number of Internal Nodes can find the other 2 at instant.	In complete binary tree there is no relating connection among these 3 attributes.
5. leaf level	Not necessarily have to be in the same depth.	Tree must have the entire leaves node in the exact same depth.

what is Binary Search Tree (BST) in Data Structure?

binary search tree (BST):
a node-based data structure, which at most can have two child nodes counting from the left child. also known as Ordered or Sorted Binary Search Tree.

properties:

• each child must be either a leaf node or the root of another binary search sub tree.
• left sub-tree can contain only nodes, whom are less than the parent node.
• right sub-tree can contain only nodes, whom are greater than the parent node
• non of the nodes can be alike.

diagram:

specialties:

• basis for many of highly efficient sorting and searching algorithms
• can be used to construct abstract data structures including sets, multi-sets, associative arrays etc.

UVA sloved: problem number: 10055 - Hashmat the Brave Warrior

question:

Problem A

Hashmat the brave warrior

Input: standard input

Output: standard output

Hashmat is a brave warrior who with his group of young soldiers moves from one place to another to fight against his opponents. Before fighting he just calculates one thing, the difference between his soldier number and the opponent's soldier number. From this difference he decides whether to fight or not. Hashmat's soldier number is never greater than his opponent.

Input

The input contains two integer numbers in every line. These two numbers in each line denotes the number of soldiers in Hashmat's army and his opponent's army or vice versa. The input numbers are not greater than 2^32. Input is terminated by End of File.

Output

 For each line of input, print the difference of number of soldiers between Hashmat's army and his opponent's army. Each output should be in seperate line.

Sample Input:

10 12
10 14
100 200

Sample Output:

2
4
100

how to access Google USA [ some might call it Original Google Head Office's server ] from any other country?

this question has been bugging me for a long time, i think i should share the best way to fix it with everyone.

for this you can change 'preference' form your Google account or can do many of hubble bubble stupid 'setting' stuffs.

OR

you can just use www.google.com/ncr to get access the USA Google server network (or you may call it the main Google server).

thank you :)
