TRANSITIONS OF MATRIX

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

Smallest example: the smallest TRANSITIONS OF MATRIX example you can type. Type it, run it, and say what you see. If you can do that from memory, you know TRANSITIONS OF MATRIX.

From the example next to this theory: TRANSITIONS OF MATRIX — arrays give O(1) index access; matrices are arrays of arrays.

Trap — only saying “TRANSITIONS OF MATRIX” with no example. Fix that before you talk about advanced DSA.

Viva: what is TRANSITIONS OF MATRIX? Then show the smallest TRANSITIONS OF MATRIX example you can type. Then name the trap.

Exam tip

What is TRANSITIONS OF MATRIX? Show this: the smallest TRANSITIONS OF MATRIX example you can type. Trap: only saying “TRANSITIONS OF MATRIX” with no example.

Example

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

TRANSITIONS OF MATRIX — arrays give O(1) index access; matrices are arrays of arrays.
