Print Matrix in a Snake Pattern

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

Smallest example: the smallest Print Matrix in a Snake Pattern example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Print Matrix in a Snake Pattern.

From the example next to this theory: Print Matrix in a Snake Pattern — arrays give O(1) index access; matrices are arrays of arrays.

Trap — only saying “Print Matrix in a Snake Pattern” with no example. Fix that before you talk about advanced DSA.

Viva: what is Print Matrix in a Snake Pattern? Then show the smallest Print Matrix in a Snake Pattern example you can type. Then name the trap.

Exam tip

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