Strassen's Matrix Multiplication

Strassen's Matrix Multiplication is a DSA idea you prove with Strassen's Matrix Multiplication on Farhan's board, not with a slogan.

Strassen's Matrix Multiplication on the board: one Strassen's Matrix Multiplication step Farhan can write from memory. Then say what Strassen's Matrix Multiplication on Farhan's board looks like after.

Strassen's Matrix Multiplication exists so Farhan can keep Strassen's Matrix Multiplication on Farhan's board correct in a viva board.

Farhan ships Strassen's Matrix Multiplication in a viva board. That is the use case worth saying.

If Strassen's Matrix Multiplication on Farhan's board breaks under Strassen's Matrix Multiplication, check skipping the failure case for Strassen's Matrix Multiplication first.

Strassen's Matrix Multiplication is not a lonely heading. Farhan ties it to Strassen's Matrix Multiplication on Farhan's board.

One breath for Strassen's Matrix Multiplication, then Strassen's Matrix Multiplication on Farhan's board, then skipping the failure case for Strassen's Matrix Multiplication. Sit down.

Exam tip

Say Strassen's Matrix Multiplication in one breath, then one Strassen's Matrix Multiplication step Farhan can write from memory, then skipping the failure case for Strassen's Matrix Multiplication.

Example

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

Strassen's Matrix Multiplication — arrays give O(1) index access; matrices are arrays of arrays.
