Your recording

Your transcript

So, concepts is basically when you... uh... use it for solving problems. I think the main idea is that it works by, like, breaking things down. For example, if you had a list, you'd just iterate and apply the logic.

Better answer

Concepts is best understood as a technique that trades memory for time. Start by stating the definition, then give a 2-line example, then mention complexity (typically O(n log n) for the common case), and close with one trade-off such as space overhead or sensitivity to input order.
