Algorithmic Thinking: A Problem-Based Introduction
What is Algorithmic Thinking?
Algorithmic thinking is a fundamental skill in computer science and problem solving. It is the ability to identify and solve problems by developing algorithms, which are step-by-step instructions for carrying out a task.

Algorithmic thinking is used in many different areas of life, such as:
- Computer programming
- Problem solving
- Decision making
- Planning
- Scheduling
- Design
- Optimization
Why is Algorithmic Thinking Important?
Algorithmic thinking is important because it allows us to:
- Solve problems more efficiently
- Develop more effective solutions
- Understand the world around us better
- Prepare for careers in computer science and other STEM fields
How to Develop Algorithmic Thinking Skills
Algorithmic thinking skills can be developed by practicing problem solving and algorithm development. There are many different ways to practice these skills, such as:
- Solving coding problems
- Working on puzzles and brain teasers
- Participating in hackathons and coding competitions
- Taking online courses in algorithmic thinking and problem solving
- Reading books and articles about algorithmic thinking
Problem-Based to Algorithmic Thinking
The following are some problems that can be used to introduce algorithmic thinking:
Problem 1: How to find the sum of the first n natural numbers?
Problem Analysis: The first step is to analyze the problem and understand what we need to do. In this case, we need to find a way to add up the first n natural numbers.
Problem Decomposition: The next step is to decompose the problem into smaller subproblems. In this case, we can decompose the problem into the following subproblems:
1. Define a base case. 2. Define a recursive case. 3. Implement the algorithm.
Problem Representation: The following algorithm represents a solution to the problem:
python def sum_of_n_natural_numbers(n): if n == 1: return 1 else: return n + sum_of_n_natural_numbers(n - 1)
Problem 2: How to find the factorial of a number?
Problem Analysis: The first step is to analyze the problem and understand what we need to do. In this case, we need to find a way to find the factorial of a number.
Problem Decomposition: The next step is to decompose the problem into smaller subproblems. In this case, we can decompose the problem into the following subproblems:
1. Define a base case. 2. Define a recursive case. 3. Implement the algorithm.
Problem Representation: The following algorithm represents a solution to the problem:
python def factorial(n): if n == 0: return 1 else: return n * factorial(n - 1)
Problem 3: How to find the greatest common divisor of two numbers?
Problem Analysis: The first step is to analyze the problem and understand what we need to do. In this case, we need to find a way to find the greatest common divisor of two numbers.
Problem Decomposition: The next step is to decompose the problem into smaller subproblems. In this case, we can decompose the problem into the following subproblems:
1. Define a base case. 2. Define a recursive case. 3. Implement the algorithm.
Problem Representation: The following algorithm represents a solution to the problem:
python def gcd(a, b): if b == 0: return a else: return gcd(b, a % b)
