MCQs on backtracking

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

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

From the example next to this theory — MCQs on backtracking: dry-run [4, 1, 3].

Trap — only saying “MCQs on backtracking” with no example. Fix that before you talk about advanced DSA.

Viva: what is MCQs on backtracking? Then show the smallest MCQs on backtracking example you can type. Then name the trap.

Exam tip

What is MCQs on backtracking? Show this: the smallest MCQs on backtracking example you can type. Trap: only saying “MCQs on backtracking” with no example.

Example

# MCQs on backtracking
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)

MCQs on backtracking: dry-run [4, 1, 3]. Say the list after one step.
