Every problem I track, by pattern, with a one-line insight. 20 tracked so far, plus my LeetCode stats.

Multi-part coding questions in the style real rounds ask, each with the full question and Java code for every part.

Low-level design problems built end to end in Java: entities, design patterns, thread safety and a runnable demo.

How do I add a problem here?

Just write it in IntelliJ and refresh this page. These folders are read automatically:

~/Desktop/code_practice/src/main/java/com/practice/phonepe/questions: each package is an LLD problem
~/Desktop/code_practice/src/main/java/com/practice/phonepe/interview: one LLD problem
~/Desktop/code_practice/problems/src/main/java/lld: each package is an LLD problem
~/Desktop/code_practice/problems/src/main/java/dsa: each file or folder is a DSA problem
~/IdeaProjects/personalProject/miniproject/src/main/java: each package is an LLD problem

Optional: start a DSA file with a comment like /** Problem: Two Sum Link: https://… Difficulty: Easy */ to show a link and difficulty.
