Introduction to Algorithms Quiz

What is an algorithm?

• A step-by-step procedure to solve a problem

• A software program

• A programming language

• A computer hardware component

Which of the following is NOT a characteristic of a good algorithm?

• Finiteness

• Infinite loops

• Definiteness

• Input/output

What does 'definiteness' mean in the context of algorithms?

• The algorithm must always give output

• Each step must be clearly defined

• It must take at least one input

• The algorithm must run forever

Which of the following is true about algorithms?

• Algorithms must have at least one input and one output

• Algorithms are written only in high-level languages

• Algorithms must always be converted to flowcharts

• Algorithms never end

What is 'finiteness' in algorithms?

• It must end after a finite number of steps

• It must run infinitely

• It must repeat steps

• It must accept infinite inputs

Which of the following is a valid reason to use pseudocode?

• To execute a program directly

• To describe logic before coding

• To debug hardware issues

• To replace flowcharts

Pseudocode is written in:

• A formal programming language

• Machine language

• A combination of English and programming logic

• Binary code

Which of the following is an example of an algorithm?

• Recipe for baking a cake

• HTML webpage

• A keyboard

• Computer virus

What distinguishes an algorithm from a program?

• Algorithms are hardware-dependent

• Programs cannot have logic

• Algorithms are logic-based steps; programs are coded implementations

• There is no difference

Which is NOT part of the five characteristics of an algorithm?

• Input

• Output

• Clarity

• Color
