Round 1
Questions:
- Serialize multilevel linked list - discussed multiple approaches and time complexity (TC), space complexity (SC). The interviewer told me not to code.
- Longest substring without repeating characters - coded and passed test cases. Discussed TC and SC.
Candidate's Approach
For the longest substring without repeating characters, I implemented a sliding window technique to keep track of the characters and their indices, ensuring that I efficiently found the length of the longest substring.
