Problem $2.(20$ points$)$

We know the format of lw$-$format instruction:

$101011$ss ssst tttt IIII IIII IIII IIII$$ sw rt$,$ I $($rs$)$

We know the format of$$beq$$instruction:

$000100$ss ssst tttt iiii iiii iiii iiii$$ beq rs$,$rt$,$I

$$

The format can also be presented as follows:

$$

$$

Processor tries to run instruction sw$$$$6,8($$$5),$ please answer the following question:

$$The$$instruction$$sw$$$$6,8($$$5)$allocates$$at memory address$0$x$00400018.$

The data memory has the following structure:

$$
