This repository presents updated and modernized solutions to programming challenges found in Harry He's "Coding Interviews" book, which is a well-regarded resource for candidates preparing for coding interviews. The book can be purchased on Amazon here.

Here are some specific aspects I focused on while modernizing the solutions:

1. Error Handling: Replaced error codes with exceptions to handle errors more gracefully.
2. Input/Output: Used iostream instead of stdlib.h for standard input and output operations.
3. Testing: Swapped console tests with assertions to validate the solutions.
4. Data Structures: Preferred using vectors over bare arrays for flexibility.
5. Looping: Used iterators instead of integer counters for traversing collections.
6. Class Implementation: Implemented collections using classes to encapsulate data.
7. References: Used references instead of pointers where possible for safety and readability.
8. Functional Programming: Employed lambdas for implementing private functions.
9. Simplifying Data: Used STL pairs instead of creating custom structs.
10. Type Deduction: Utilized the auto keyword for cleaner code and type deduction.

While I've endeavored to improve the solutions, it is important to note that:

• This repository does not provide solutions to every problem mentioned in the book.
• Some solutions in this repository may not correspond to problems directly from the book but are inspired by similar challenges.

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.

Please make sure to update tests as appropriate.
