Check if the given string is K-periodic

Check if the given string is K-periodic is a DSA topic. In plain words you use it for a short Check if the given string is K-periodic example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Check if the given string is K-periodic example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Check if the given string is K-periodic.

From the example next to this theory — Check if the given string is K-periodic: dry-run [4, 1, 3].

Trap: only saying “Check if the given string is K-periodic” with no example. Fix that before you talk about advanced DSA.

Viva: what is Check if the given string is K-periodic? Then show the smallest Check if the given string is K-periodic example you can type. Then name the trap.

Exam tip

What is Check if the given string is K-periodic? Show this: the smallest Check if the given string is K-periodic example you can type. Trap: only saying “Check if the given string is K-periodic” with no example.

Example

# Check if the given string is K-periodic
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)

Check if the given string is K-periodic: dry-run [4, 1, 3]. Say the list after one step.
