Large matrix multiplication

Multiply two square matrices as fast as possible.

Input

Two 2000 x 2000 matrices of uint32 values on STDIN, encoded back-to-back in row-major order, little-endian byte order.

Output

Write the resulting 2000 x 2000 product matrix to STDOUT in the same binary format (row-major, little-endian uint32).
