kdn251/interviews ? reverse-engineered prompt

Build me a Java interview prep repo that helps someone study for coding interviews and practice common algorithm problems. I want it organized by topic, with clear examples for data structures and algorithms like linked lists, stacks, queues, trees, heaps, hashing, greedy, bit manipulation, and runtime analysis.

Please include solution files for interview style problems, grouped in a way that is easy to browse by source, like LeetCode, company questions, Cracking the Coding Interview, and a few UVA style practice problems. Add simple explanations in the README so a learner can understand the idea behind each solution, not just copy the code. If it makes sense, include visuals or links for the core data structures.

Keep everything in Java, and make the project feel like a clean study guide that someone could use to prep for technical interviews. If you need to check current Java or interview problem conventions, look them up online first.
