Hello,

BBRICKS — link

in the editorial for the problem BBRICKS one of the guy posted his solution which uses matrix exponentiation to solve the problem and i couldn't make much from his solution on how to solve the question using matrix exponentiation, so if anyone could please just tell me how this problem can be solved using matrix exponentiation.

solution which uses matrix exponentiation

Even the editorialist has no clue on how to solve it using matrix exponentiation.

Thanks in advance :)
