3Round 1: Coding Assessment
1. **Array Manipulation:**
- Task: Implement a function to rotate an array by K steps to the right.
- Constraints: Use constant space.
2. **String Manipulation:**
- Task: Given two strings, determine if they are anagrams.
- Constraints: Optimize for time complexity.
3. **Linked List Operations:**
- Task: Write a function to reverse a linked list.
- Constraints: Implement it iteratively.
Candidates will be evaluated based on correctness, efficiency, and coding style. Successful completion moves to the next round.
