Round 1

Questions:

Question 1:

This question involved string parsing, regex, HashMap, and HashSet. It was challenging to build intuition, and it took some time. I managed to pass 7 out of 8 test cases.

Question 2:

This question was based on JSON string parsing, regex and the carry-forward technique. It was easier compared to the first one. I passed 9 out of 10 test cases.

I debugged my solutions and believe my approach for the failed test cases is correct. However, since the expected output was hidden, I couldn’t confirm it fully.
