Code Lab Module2 (GDSC Elizade University)

This session equips you with the foundational skills of Algorithmic Thinking.

1. Code Lab Module 2: Algorithmic Thinking Opeoluwa Daniel Oyedeji GDSC Lead, E.U. Elizade University

2. What is an Algorithm? Algorithmic Thinking

3. An algorithm is a set of instructions to solve a well-defined problem.

4. Basic algorithmic concepts Algorithmic Thinking

5. Basic algorithmic concepts Sequencing Selection (if/else) Loops (for/while) Functions Recursion

6. Sequencing This is like following a recipe step-by-step. Instructions execute one after another. Instructions execute in the order they are written.

7. Selection (if/else) Imagine a decision point. This checks a condition and executes different instructions based on whether the condition is true or false. If it is raining wear a raincoat. Else wear sunscreen.

8. Loops (for/while) Think of repeating a task a certain number of times (for loop) or until a condition is met (while loop). W atering your plants every day (for loop). Continuing to search for something until you find it (while loop).

9. Functions These are reusable blocks of code that perform a specific task. Think of them as tools in your coding toolbox. You can give them a name and use them throughout your code whenever you need that task done.

10. Recursion Imagine a function calling itself! It solves a problem by breaking it down into smaller versions of the same problem, until it reaches a simple case. Base Case: Simplest problem, recursion stops here. Recursive Case: Calls itself with a smaller problem.
