Print a given matrix in spiral form

Print a given matrix in spiral form (alt) is a DSA topic. In plain words you use it for a short Print a given matrix in spiral form alt example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Print a given matrix in spiral form alt example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Print a given matrix in spiral form (alt).

From the example next to this theory: Print a given matrix in spiral form (alt) — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Print a given matrix in spiral form alt” with no example. Fix that before you talk about advanced DSA.

Viva: what is Print a given matrix in spiral form (alt)? Then show the smallest Print a given matrix in spiral form alt example you can type. Then name the trap.

Exam tip

What is Print a given matrix in spiral form (alt)? Show this: the smallest Print a given matrix in spiral form alt example you can type. Trap: only saying “Print a given matrix in spiral form alt” with no example.

Example

arr = [10, 20, 30, 40]
print(arr[2], arr[-1])
matrix = [[1, 2], [3, 4]]
print(matrix[1][0])  # 3

Print a given matrix in spiral form (alt) — arrays give O(1) index access; matrices are arrays of arrays.
