Below are some HackerRank problems. The main purpose of sharing these is to highlight an important point: in company exams, writing code is not enough—you must pass all test cases, including hidden ones. If even a single test case fails, you won’t receive full marks.

To consistently pass all test cases, practice is essential. I’ll be uploading more problems in the coming days to help you prepare and confidently crack any exam.

I always believe in one principle:
"Practice makes code perfect."
