What is an algorithm?
Click to flip
An algorithm is a set of instructions designed to perform a specific task.
Click to flip
Why are algorithms important in computer science?
Click to flip
Algorithms are important because they provide a clear method to solve problems efficiently and are the foundation of computer programming.
Click to flip
Give an example of a simple daily life algorithm.
Click to flip
An example is a recipe for baking a cake: gathering ingredients, mixing them, and cooking are steps in an algorithm.
Click to flip
What are the two main types of algorithms?
Click to flip
The two main types are iterative algorithms and recursive algorithms.
Click to flip
What is the difference between an iterative and a recursive algorithm?
Click to flip
An iterative algorithm repeats a certain task using loops, while a recursive algorithm solves problems by calling itself until it reaches a base case.
Click to flip
Define a ‘step’ in the context of an algorithm.
Click to flip
A 'step' is a single instruction that is part of a sequence in an algorithm.
Click to flip
What does it mean if an algorithm is efficient?
Click to flip
An efficient algorithm solves a problem with the least amount of resources, like time and memory.
Click to flip
What is pseudocode?
Click to flip
Pseudocode is a way to describe algorithms using a mixture of natural language and programming language details to make the process easier to understand.
Click to flip
Explain what a flowchart is used for in algorithms.
Click to flip
A flowchart is a visual representation of an algorithm, showing the sequence of steps using symbols and arrows.
Click to flip
What is the purpose of using loops in algorithms?
Click to flip
Loops are used to repeat a set of instructions until a certain condition is met.
Click to flip
Name a real-world example of an algorithm in technology.
Click to flip
A search engine like Google uses algorithms to rank websites.
Click to flip
Can an algorithm have multiple solutions?
Click to flip
Yes, some problems can be solved by multiple algorithms, each with different efficiencies.
Click to flip
What is a conditional statement and how is it used in algorithms?
Click to flip
A conditional statement is a programming command that performs different actions depending on whether a condition is true or false, often using 'if' or 'else' statements.
Click to flip
Why is debugging important in working with algorithms?
Click to flip
Debugging is important because it helps identify and fix errors in the algorithm to ensure it works as intended.
Click to flip
What role do variables play in algorithms?
Click to flip
Variables store data that can be accessed and modified during the execution of an algorithm.
