(8 points) Represent (in binary and separately) the decimal signed whole numbers 436 and - 436 in each of the following formats: (a) sign-magnitude. (b) l's complement (c) 2's complement (d) excess-511 For Parts (a), (b) and (c), use the minimum number of bits necessary; for Part (d), use the same number of bits as in Parts (a), (b) and (c). CAUTION: You will earn NO CREDITS if you simply show the final result and not clearly show working (i.e., intermediate steps). (If you use the result from a previous question, indicate the question number and intermediate steps already shown to arrive at that result can be skipped.)
