Interview Prompt
A text-cleaning step reduces words to known stems before indexing. Given a list of root words and a whitespace-separated sentence, replace each word that begins with one of the roots by that root, and return the rewritten sentence.
Summary
Every word trimmed to its root.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
