Leetcode questions are not selected for novelty. In fact, the best way to get a problem turned into a Leetcode question is to post it to Leetcode’s discussion board and say someone asked you it in an interview at a big tech company. So it’s still possible that some or even many these questions appear nearly verbatim in the training data.
