Code review checklist for LLD - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if the design follows the {{BLANK_1}} principle.

LLD

if design.adheres_to("[1]"):
    print("Design is modular and easy to maintain.")

ASingle Responsibility

BOpen-Closed

CLiskov Substitution

DDependency Inversion

💡 Hint

Common Mistakes

Confusing Single Responsibility with Open-Closed principle.

The Single Responsibility Principle ensures each module has one clear responsibility, making the design modular and maintainable.

2fill in blank

medium

Complete the code to validate if the design uses {{BLANK_1}} to reduce tight coupling.

LLD

if design.uses("[1]"):
    print("Design is loosely coupled.")

Drag options to blanks, or click blank then click option'

Ainheritance

Bhardcoded dependencies

Cglobal variables

Dinterfaces

Attempts:

💡 Hint

Common Mistakes

Choosing inheritance which can increase coupling.

Using interfaces helps reduce tight coupling by allowing modules to interact through abstractions.

3fill in blank

hard

Fix the error in the checklist code to ensure {{BLANK_1}} is properly checked.

LLD

if not design.has_clear_[1]():
    raise ValueError("Design lacks clarity in this aspect.")

Drag options to blanks, or click blank then click option'

Anaming

Bcomments

Cinterfaces

Ddependencies

💡 Hint

Common Mistakes

Checking interfaces instead of naming clarity.

Clear naming is essential for understanding design elements easily.

4fill in blank

hard

Fill both blanks to verify design {{BLANK_1}} and {{BLANK_2}}.

LLD

if design.has_[1]() and design.is_[2]():
    print("Design is scalable and maintainable.")

Drag options to blanks, or click blank then click option'

Amodularity

Bperformance

Cextensible

Dtestable

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing performance or testable which are important but not the focus here.

Modularity and extensibility are key for scalable and maintainable designs.

5fill in blank

hard

Fill all three blanks to check design {{BLANK_1}}, {{BLANK_2}}, and {{BLANK_3}}.

LLD

if design.is_[1]() and design.has_[2]() and design.supports_[3]():
    print("Design meets quality standards.")

Drag options to blanks, or click blank then click option'

Atestable

Bdocumentation

Cscalability

Dsecurity

Attempts:

💡 Hint

Common Mistakes

Confusing security with scalability or testability.

Testability, documentation, and scalability are crucial for high-quality designs.
