In class, we examined an algorithm to generate the 2’sC of an integer (flip all bits; add 1). We also saw how any number in binary can be directly represented in hex. Putting the above two together, work out an algorithm that takes a number in hex and directly obtains its 2’sC representation in hex (e.g. 0xBEEF →0x4111). Justify your answer - i.e. give reason(s) why your algorithm works correctly

Question

In class, we examined an algorithm to generate the 2’sC of an
integer (flip all bits; add 1). We also saw how any number in binary can
be directly represented in hex. Putting the above two together, work
out an algorithm that takes a number in hex and directly obtains its
2’sC representation in hex (e.g. 0xBEEF →0x4111). Justify your
answer - i.e. give reason(s) why your algorithm works correctly
