🔍 What is an Algorithm?

An Algorithm is a step-by-step procedure or a set of rules designed to solve a specific problem or accomplish a particular task. It’s like a cooking recipe that tells you what to do, one step at a time.

Example: Making a Cup of Tea

1. Boil water.
2. Add tea leaves to the boiled water.
3. Let it simmer for a few minutes.
4. Add milk and sugar.
5. Strain the tea.
6. Serve hot.

This simple recipe is an algorithm in everyday life!

📌 Characteristics of a Good Algorithm

1. Input: It takes some input(s).
2. Output: It produces at least one output.
3. Definiteness: Every step is clearly defined.
4. Finiteness: It ends after a finite number of steps.
5. Effectiveness: Each step is simple and precise.

💡 Writing Algorithms (Pseudocode)

Pseudocode is a way of writing algorithms in a simple, human-readable form. It’s not actual code but a structured outline of the logic.

Example: Adding Two Numbers

Problem: Add two numbers and display the result.

Pseudocode:

START
  Read A, B
  Sum = A + B
  Display Sum
END

🔄 Flow Diagrams

Flow diagrams (flowcharts) visually represent algorithms, making them easier to understand.

Example: Algorithm for Finding the Largest of Two Numbers

1. Start
2. Input A, B
3. If A > B, Print A
4. Else, Print B
5. End

📝 Pseudocode for Finding Largest of Two Numbers

START
  Read A, B
  IF A > B THEN
    Print A
  ELSE
    Print B
  ENDIF
END
