Pair of strings having longest common prefix of maximum length in given array

Pair of strings having longest common prefix of maximum length in given array is a DSA topic. In plain words you use it for a short Pair of strings having longest common prefix of maximum length in given array example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Pair of strings having longest common prefix of maximum length in given array example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Pair of strings having longest common prefix of maximum length in given array.

From the example next to this theory: Pair of strings having longest common prefix of maximum length in given array — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Pair of strings having longest common prefix of maximum length in given array” with no example. Fix that before you talk about advanced DSA.

Viva: what is Pair of strings having longest common prefix of maximum length in given array? Then show the smallest Pair of strings having longest common prefix of maximum length in given array example you can type. Then name the trap.
