Appeared for a phone screen round for google, i was asked a question related to traversing n-ary tree (straightforward easy), was able to solve it.
I asked about what kind of structure i will get as input, but the interviewer said i can choose it, so i took time to construct the structure of tree , and fumbled in creating the class for creating tree, there was no time for solving the follow up question but i recieved a positive feedback.
