Introduction to Algorithms #
Welcome to Day 1 of our 60 Days of Coding Algorithm Challenge! Today, we’ll start with the basics: What is an algorithm?
What is an Algorithm? #
An algorithm is a step-by-step procedure or formula for solving a problem. It’s a set of instructions that takes some input, performs a series of steps, and produces an output.
Key Characteristics of Algorithms #
- Input: An algorithm must have zero or more inputs.
- Output: An algorithm should produce at least one output.
- Definiteness: Each step must be precisely defined.
- Finiteness: The algorithm must terminate after a finite number of steps.
- Effectiveness: Each step must be simple enough to be carried out by a human using pencil and paper.
Example: Simple Addition Algorithm #
Let’s look at a simple algorithm for adding two numbers:
- Start
- Input two numbers, A and B
- Set SUM = A + B
- Output SUM
- End
This simple algorithm takes two inputs, performs one operation, and produces one output.
Why Are Algorithms Important? #
Algorithms are the foundation of computer science and are crucial for several reasons:
- Problem Solving: They provide a systematic approach to …
