Pull Request Overview
This PR implements a solution for the "Contains Duplicate" LeetCode problem using a HashSet-based approach to detect duplicate elements in an array.
- Adds a Java solution that uses HashSet to track visited elements
- Leverages the HashSet.add() method's return value to efficiently detect duplicates
- Returns true immediately when a duplicate is found, false when all elements are unique
Comments suppressed due to low confidence (1)
contains-duplicate/shinheekim.java:8
- [nitpick] The variable name 'n' is too generic and unclear. Consider using a more descriptive name like 'num' or 'element' to improve code readability.
