-## Haskell GHCi Interpreter - Lecture Notes
-
-### Introduction (5 minutes)
-- Welcome and brief overview of the session.
-- Introduction to Haskell and GHCi (Glasgow Haskell Compiler Interactive).
-
-### Getting Started with GHCi (10 minutes)
-### Installation
-- Mention how to install Haskell and GHCi.
-
-#### Opening GHCi
-- Open GHCi in the terminal or command prompt.
-
-#### Basic Commands
-- `:load` or `:l` to load a Haskell file.
-- `:reload` or `:r` to reload the loaded file.
-- `:quit` or `:q` to exit GHCi.
-
-### Haskell Basics (10 minutes)
-#### Variables and Types
-- Declare variables using `let`.
-- Basic data types: `Int`, `Double`, `Char`, `Bool`.
-
-#### Functions
-- Define functions using `let`.
-- Example functions and their types.
-
-#### Lists
-- Create lists and perform basic operations.
-- List comprehensions.
-
-### Interactive Coding Session (10 minutes)
-- Demonstrate live coding in GHCi.
-- Solve a simple problem or implement a small program interactively.
-
-### Advanced GHCi Features (5 minutes)
-#### Type Information
-- Use `:type` or `:t` to get the type of an expression.
-
-#### Documentation
-- Access Haddock documentation in GHCi.
-
-#### Debugging
-- Utilize GHCi for debugging Haskell code.
-
-### Conclusion (5 minutes)
-- Recap of key points.
-- Resources for further learning.
-- Q&A.

-## Haskell Functions and Types - Lecture Notes
-
-### Introduction (5 minutes)
-- Welcome and brief overview of the session.
-- Importance of functions and types in Haskell.
-
-### Functions in Haskell (15 minutes)
-
-#### Function Declaration
-- Syntax: `functionName :: Type1 -> Type2 -> ... -> ReturnType`
-- Example:
-```haskell
-add :: Int -> Int -> Int
-add x y = x + y
-```
-
-#### Function Application
-- Applying functions with space.
-- Example:
-```
-result = add 3 5
-
-```
-
-#### Currying
-- Explanation of curried functions.
-- Example:
-```
-add :: Int -> (Int -> Int)
-add x y = x + y
-```
-
-#### Anonymous Functions (Lambda)
-- Syntax: \parameter -> expression
-- Example:
-```
-square = \x -> x * x
-```
-
-#### Higher-Order Functions
-- Functions that take functions as arguments or return functions.
-- Example:
-```
-applyTwice :: (a -> a) -> a -> a
-applyTwice f x = f (f x)
-```
-
-### Types in Haskell (15 minutes)
-#### Type Declaration
-- Explicit type declarations.
-- Example:
-```
-add :: Int -> Int -> Int
-add x y = x + y
-```
-
-#### Common Types
-- Int, Integer, Double, Char, Bool, Lists.
-- Examples:
-```
-numbers :: [Int]
-chars :: String
-```
-
-#### Polymorphism
-- Type variables and polymorphic functions.
-- Example:
-```
-identity :: a -> a
-identity x = x
-```
-
-#### Custom Data Types
-- Defining data types with data keyword.
-- Example:
-```
-data Point = Point Float Float
-distance :: Point -> Point -> Float
-```

-### Interactive Coding Session (5 minutes)
-- Demonstrate live coding in GHCi.
-- Solve a simple problem or implement a small program interactively.
-
-### Conclusion (5 minutes)
-- Recap of key points on functions and types.
-- Emphasize the importance of type safety in Haskell.
-- Resources for further learning.
-- Q&A.
