Insertion at end

Insertion at end (dll) is a DSA topic. In plain words you use it for a short Insertion at end dll example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Insertion at end dll example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Insertion at end (dll).

From the example next to this theory — Insertion at end (dll) — Dry-run [4, 1, 3].

Trap — only saying “Insertion at end dll” with no example. Fix that before you talk about advanced DSA.

Viva: what is Insertion at end (dll)? Then show the smallest Insertion at end dll example you can type. Then name the trap.

Exam tip

What is Insertion at end (dll)? Show this: the smallest Insertion at end dll example you can type. Trap: only saying “Insertion at end dll” with no example.

Example

# Insertion at end
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Insertion at end (dll) — Dry-run [4, 1, 3]. Say the list after one step.
