Round Summary
Got 2 coding questions in my interview:

1. Valid Word Abbreviation
- Spent most of the time (~30 mins) on this one.
- Interviewer asked me to list all possible test cases — I gave several, but missed the case with a 0 in the abbreviation. He pointed it out, and I updated my code to handle it.
- Not sure if missing it initially will count against me.

2. Pow(x, n)
- This was given when very little time was left, so I was a bit nervous.
- I first explained the brute force approach, then moved on to the O(log n) optimized approach.
- Got slightly confused while discussing space complexity.
