Algorithm - Answer- A computable set of steps to achieve a desired result.
Array - Answer- In programming, a list of data values, all of the same type, any
element of which can be referenced by an expression consisting of the array name
followed by an indexing expression. Arrays are part of the fundamentals of data
structures, which, in turn, are a major fundamental of computer programming
Data Structure - Answer- The term data structure refers to the way data is organized
for use within a program. Correct organization of data can lead to simpler and more
efficient algorithms. Common data structures are linked-lists, stacks, queues and
trees.
FIFO - Answer- First in first out is a policy that items are processed in order of
arrival. A QUEUE implements this.
Insertion Sort - Answer- Sort by repeatedly taking the next item and inserting it into
the final data structure in its proper order with respect to items already inserted.
LIFO - Answer- Last in first out is a policy that the most recently arrived item is
processed first. A STACK implements this.
Linked List - Answer- A data structure in which a list of nodes or elements of a data
structure connected by pointers. A singly linked list has one pointer in each node
pointing to the next node in the list; a doubly linked list has two pointers in each node
pointing to the next and previous nodes. In a circular list, the first and last nodes of
the list are linked together.
Linear Search - Answer- A simple, though inefficient, search algorithm that operates
by sequentially examining each element in a list until the target element is found or
the last has been completely processed. Linear searches are primarily used only
with very short lists. Also called sequential search.
merge sort - Answer- A sort algorithm that splits the items to be sorted into two
groups, recursively sorts each group, and merges them into a final, sorted sequence.
Node - Answer- A unit of reference in a data structure. Also called a vertex in graphs
and trees. (2) A collection of information which must be kept at a single memory
location.
Infix Notation - Answer- Notation in which the operator separates its operands. E.g.
(a + b) * c. Infix notation requires the use of brackets to specify the order of
evaluation, unlike either prefix or postfix notations.
Postfix Notation - Answer- Reverse Polish Notation or Suffix Notation Notation in
which the operator follows its operands. E.g. a + b * c represented as abc*+.
