What is iteration

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

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

From the example next to this theory — What is iteration: dry-run [4, 1, 3].

Trap — only saying “iteration what is” with no example. Fix that before you talk about advanced DSA.

Viva — what is iteration (what is)? Then show the smallest iteration what is example you can type. Then name the trap.

Exam tip

What is iteration (what is)? Show this: the smallest iteration what is example you can type. Trap: only saying “iteration what is” with no example.

Example

# What is iteration
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)

What is iteration: dry-run [4, 1, 3]. Say the list after one step.
