Practice Problem $217$

In Chapter $3,$ we will look at listings generated by a disassembler, a program

that converts an executable program file back to a more readable ASCII form.

These files contain many hexadecimal numbers, typically representing values

in two's$-$complement form. Being able to recognize these numbers and under$-$

stand their significance $($for example, whether they are negative or positive$)$ is

an important skill.

For the lines labeled $A-K($on the right$)$ in the following listing, convert the

hexadecimal values shown to the right of the instruction names $($sub$,$ push,

mov, and add$)$ into their decimal equivalents.
