Types of Sparse Matrices

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

Smallest example: the smallest Types of Sparse Matrices example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Types of Sparse Matrices.

From the example next to this theory: Types of Sparse Matrices — arrays give O(1) index access; matrices are arrays of arrays.

Trap — only saying “Types of Sparse Matrices” with no example. Fix that before you talk about advanced DSA.

Viva: what is Types of Sparse Matrices? Then show the smallest Types of Sparse Matrices example you can type. Then name the trap.

Exam tip

What is Types of Sparse Matrices? Show this: the smallest Types of Sparse Matrices example you can type. Trap: only saying “Types of Sparse Matrices” with no example.

Example

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

Types of Sparse Matrices — arrays give O(1) index access; matrices are arrays of arrays.
