- Q1. Explain treeset working
- Ans.
TreeSet is a class in Java that implements the Set interface using a tree for storage.
TreeSet stores elements in sorted order based on their natural ordering or a custom Comparator.
It does not allow duplicate elements.
Operations like add, remove, and search have O(log n) time complexity.
Example: TreeSet
treeSet = new TreeSet<>();
- Q2. Explain hashmap working
- Ans.
HashMap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
HashMap uses a hash function to map keys to indices in an array called buckets.
Collisions can occur when multiple keys hash to the same index, which is resolved using techniques like chaining or open addressing.
HashMap provides constant-time complexity O(1) for basic operations like get, put, and remove.
