Sum Of Distances

Sum Of Distances is a DSA topic. In plain words you use it for a short Sum Of Distances example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Sum Of Distances example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Sum Of Distances.

From the example next to this theory — Sum Of Distances: dry-run [4, 1, 3].

Trap — only saying “Sum Of Distances” with no example. Fix that before you talk about advanced DSA.

Viva — what is Sum Of Distances? Then show the smallest Sum Of Distances example you can type. Then name the trap.
