Maximum XOR

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

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

From the example next to this theory — Maximum XOR: dry-run [4, 1, 3].

Trap — only saying “Maximum XOR” with no example. Fix that before you talk about advanced DSA.

Viva — what is Maximum XOR? Then show the smallest Maximum XOR example you can type. Then name the trap.
