[Acua] For the following fragment of code, what page replacement scheme (choices: FIFO, OPR, LRU, MFU) should you recommend be used? #define OFFSET(x, y, columns) = (y * columns + x) // check if two matrices are the same int equals(IntMatrix* this, IntMatrix* Other) If (other == NULL || this == NULL) return 0; If (other->cols != this->cols || other->rows != this->rows) return 0; for(int y = 0; y < this->rows; ++y) for(int x=0; x cols; ++x) // no intentional magic; pointer arithmetic if (*(this->data + OFSET(x, y, this->cols)) != *(other->data + OFFSET(x, y, this->cols)) return 0; return 1;
