Requirements / Prerequisites
A foundational understanding of Scala programming syntax and basic constructs (variables, functions, control flow).
Familiarity with core object-oriented programming (OOP) principles like inheritance, polymorphism, and encapsulation.
An introductory grasp of functional programming (FP) concepts: immutability, pure functions, and higher-order functions.
Basic knowledge of common data structures (arrays, lists, maps, trees) and their operational complexities.
Comfort with a code editor or IDE (e.g., IntelliJ IDEA, VS Code) and executing Scala code.
A proactive learning attitude and willingness to engage with challenging algorithmic and design problems.
