Problem $3$

Initialize register $x10$ with the value $1,234,567,890($you can do this manually in the interpreter$).$ Place each

byte of register $x10$ into the first eight bits $(0$ to $7)$ of registers $x11,x12,x13,x14.$

Bits $0$ to $7$ should be in $11$

Bits $8$ to $15$ should be in $12$

Bits $16$ to $23$ should be in $x13$

Bits $24$ to $31$ should be in $14$

Problem $4$

Manually initialize $x3$ with the value $1,431,655,765($alternative $0$ s and $1$s$).$ Using a programmatically created

mask and logical operations change register $x3$ so that only the upper four bits $(28$ to $31)$ have their

previous value $(0101)$ and the rest are all $0$s$.$ For testing, this should give you a decimal value of

$1,342,177,280$ in register $x3.$ Now flip all the bits in $x3$ using a mask. This should give you a value of

$-1,342,177,281.$
