🔹 2. Master the Basics of Programming

Ensure you understand:

• Variables and data types

• Loops (for, while)

• Conditionals (if-else)

• Functions

• Arrays and Strings

🔹 3. Learn Core Data Structures

These are the building blocks:

• Arrays

• Strings

• Linked Lists

• Stacks

• Queues

• HashMaps (Dictionaries)

• Trees

• Graphs
