Thread: What's a good resource to practice Algorithms?

Hello -

I'm a beginner learning core JAVA. I'm looking for a resource for BEGINNERS (website, book, video, etc) to help me practice writing algorithms in plain English for a particular problem statement, in which I would later convert into JAVA syntax? I can't find seem to find any good resources on the web to practice writing algorithms for problem statements to test/improve my logical skills.

Can anyone share any resources that have problems statements w/ solutions? This way I could compare the algorithm I come up with against the solution and get better at writing algorithms.

Thanks in advance!

It's great that you're focusing on practicing algorithms to build your logical skills in Java! Here are some resources that can help you practice writing algorithms and compare your solutions with provided ones:

1. Books:
"Grokking Algorithms" by Aditya Bhargava:
This book is an excellent resource for beginners. It explains algorithms in a very visual and easy-to-understand way. The book also includes exercises that you can try out, with solutions provided.
"Cracking the Coding Interview" by Gayle Laakmann McDowell:
While primarily focused on interview preparation, this book provides a lot of problem statements and step-by-step solutions, which can help you practice algorithm writing.
2. Websites:
LeetCode (Easy Section):
LeetCode offers a wide range of algorithm problems, and you can start with the "Easy" section. Each problem has a discussion area where you can see various solutions and compare them with your own.
HackerRank (Algorithms Section):
HackerRank provides algorithm challenges with problem statements and test cases. You can write your own algorithms and compare them with the provided solutions.
GeeksforGeeks:
GeeksforGeeks has a section dedicated to algorithms and data structures. It provides problem statements along with detailed explanations and solutions.
Codeforces (Beginner Level Problems):
Codeforces offers competitive programming problems with a range of difficulties. Beginner-level problems can help you practice algorithmic thinking.
3. YouTube Channels:
"The Coding Train":
A beginner-friendly channel that explains algorithms and coding concepts in a fun and visual way.
"freeCodeCamp.org":
Their Java tutorial series includes problem-solving and algorithm explanations which can be very useful for beginners.
4. Interactive Learning Platforms:
Codecademy (Java Track):
Codecademy offers a Java course with algorithmic challenges embedded in the lessons, providing immediate feedback and comparison with solutions.
Khan Academy (Algorithms Section):
Khan Academy’s algorithms course offers interactive explanations and exercises, making it easier to grasp the concepts.
5. Practice Problems with Solutions:
"Introduction to Algorithms" (Cormen et al.):
Although it's a more advanced book, it contains a lot of algorithm problems with detailed solutions, which can be a great resource once you're more comfortable with the basics.
These resources should help you practice writing algorithms and improve your problem-solving skills in Java. Start with the basics and gradually move on to more complex problems as you gain confidence.
