Multidimensional Array

Isha only reaches for Multidimensional Array when Isha walking through Multidimensional Array has to stay correct in a first job task.

Multidimensional Array on the board: one Multidimensional Array step Isha can write from memory. Then say what Isha walking through Multidimensional Array looks like after.

Skip Multidimensional Array and copy-pasting Multidimensional Array without a dry-run shows up in a first job task.

Isha ships Multidimensional Array in a first job task. That is the use case worth saying.

Multidimensional Array trap: copy-pasting Multidimensional Array without a dry-run. Isha loses marks for that every viva.

After Multidimensional Array, Isha should still remember copy-pasting Multidimensional Array without a dry-run.

One breath for Multidimensional Array, then Isha walking through Multidimensional Array, then copy-pasting Multidimensional Array without a dry-run. Sit down.

Diagram

  index →  0    1    2
  array → [10,  20,  30]

Exam tip

Say Multidimensional Array in one breath, then one Multidimensional Array step Isha can write from memory, then copy-pasting Multidimensional Array without a dry-run.

Example

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

Multidimensional Array — arrays give O(1) index access; matrices are arrays of arrays.
