Data Structures and Algorithms

Finite set of instructions that specify a sequence of operations to be carried out 

• Algorithms
• Procedure
• Flowcharting
• Pseudocodes

Efficiency of an algorithm is measured by

• Time and Capacity complexity

• Time and Space complexity

• Speed and Space complexity

• Speed and Capacity complexity

A container that can hold a fixed number of items and these items should be of the same type.

• Element

• Array

• Index

What is an algorithm?

• Patterns and trends used to solve a problem

• A set of step-by-step instructions to resolve a problem

• A programming language

How can an algorithm be represented?

• As a flowchart only

• As pseudocode only

• As a flowchart or pseudocode

Which of these is not a data structure?

• Stack

• Array

• Integer

• List

What is a data structure?

• A method of arranging data
• A way of keeping data without an order?
• A "stack" only
• There is no formal definition for "Data Structure"

Data Structure is a particular way of storing and organizing data in a computer so that it can be used efficiently.

• True

• False

Example of Non-linear data structure.

• array

• tree

• queue

• stack

If the elements “A”, “B”, “C” and “D” are placed in a stack and are deleted one at a time, in what order will they be removed?

• ABCD

• DCBA

• DCAB

• ABDC
