IGCSE CS 7.Algorithmic Thinking

What is algorithmic thinking?

• A way of guessing the solution randomly

• A way of complicating the problem

• A way of getting to a solution by identifying the individual steps required

• A way of avoiding finding a solution

What is an algorithm?

• A set of rules that, when followed precisely, will lead to an answer

• A random guess

• A complicated problem

• A way to confuse the solution

What is the first step in performing a word search algorithm?

• Avoid looking for the letter 'a'

• Start randomly looking at the grid

• Check all the letters in the grid

• Find any instances of the letter 'a'

Why is randomly trying to find the letter 'a' not logical?

• It's the most efficient way

• It's not something a program would do

• It's the only way to find the letter 'a'

• It guarantees finding the word

What is the benefit of taking a logical approach in a word search algorithm?

• It is unnecessary in programming

• It is more methodical and efficient

• It is more random and unpredictable

• It is slower and less effective

How can adjacent letters be referred to in a grid?

• By their coordinates relative to the current letter

• By their alphabetical order

• By their color

• By their size

Why is it important to prevent checking cell locations beyond the edge of the grid?

• To speed up the algorithm

• To avoid errors

• To complicate the process

• To confuse the user

What is the purpose of incrementing variables 'o' and 'p' in the algorithm?

• To confuse the user

• To skip letters in the grid

• To check all the remaining letters in a word

• To slow down the process

What is the importance of comments in the code?

• To confuse the programmer

• To hide the code

• To help understand the various sections of the code

• To make the code longer

What does abstraction allow us to do in programming?

• Ignore the data

• Avoid solving problems

• Make the code more complicated

• Think about what's important and what's not
