Tree and Tree Terminology
In linear data structure, data is organized in
sequential order and in non-linear data
structure, data is organized in random order.
Tree is a very popular data structure

Link List
Linked lists are dynamic data structures where
nodes can be added, deleted or updated with a
minimal cost.
Also linked lists do not require access to a large
contiguous block of memory at c

Improve algorithm efficiency: run faster, process more data,
do something that would otherwise be impossible

Motivations
Many problems can be viewed as reaching a
goal state from a given starting point, e.g., the
farmer-wolf-goat-cabbage problem.
Often there is an underlying state space

The lower bound implies that if we hope to
sort numbers faster than O(n log n), we
cannot do it by making comparisons alone.
Is it possible to sort without making

Algebraic Expression
An algebraic expression is a legal combination of
operands and the operators.
Operand is the quantity (unit of data) on which a
mathematical operation is performed.
Operand may be a variable like x, y, z or a
