Create a matrix with alternating rectangles of O and X

Asha only reaches for Create a matrix with alternating rectangles of O and X when a Create a matrix with alternating rectangles of O and X dry-run has to stay correct in a first job task.

Do Create a matrix with alternating rectangles of O and X once by hand. one Create a matrix with alternating rectangles of O and X step Asha can write from memory. Change one input. Say the new result out loud.

Without Create a matrix with alternating rectangles of O and X, a first job task gets messy and a Create a matrix with alternating rectangles of O and X dry-run is hard to trust.

Asha ships Create a matrix with alternating rectangles of O and X in a first job task. That is the use case worth saying.

Don’t do this with Create a matrix with alternating rectangles of O and X: copy-pasting Create a matrix with alternating rectangles of O and X without a dry-run. Interviewers spot it in ten seconds.

Place Create a matrix with alternating rectangles of O and X next to nearby DSA work — one Create a matrix with alternating rectangles of O and X step Asha can write from memory is the link.

Close Create a matrix with alternating rectangles of O and X with: “If I skip it, a Create a matrix with alternating rectangles of O and X dry-run goes wrong like this: copy-pasting Create a matrix with alternating rectangles of O and X without a dry-run.”

Exam tip

For Create a matrix with alternating rectangles of O and X: definition + a first job task + one failure.

Example

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

Create a matrix with alternating rectangles of O and X — arrays give O(1) index access; matrices are arrays of arrays.
