What did you think about the exam. Heavily stimulus based and coding orientated I thought. Hardly any definition work....
I never learnt how to convert from binary to decimal for floating point, just the one way. Truth table/circuit was hard. I didn't get either marks there. I'd say I'll get 1-2 marks for the binary multiplication question, maybe 1 for the floating point and probably none for truth table/circuit. At least there wasn't flip flops.Which bit? Converting the floating point was simple, but the truth table was a bitch, but definitely do-able though.
15 I put C. {} represents 0 or more when you go back through A is before the defined B. 16 I put D.I found the paper significantly easier than previous ones, I actually spent about 5mins looking to see if I had missed a page.
I felt there was a lot of drawing and not much algorithms at all.
Confident mid-90s
Only 2 multiple choice and one question in Section II I wasn't sure one.
What did everyone put for MC15 (I put B) MC16 (I put D)?
Hardest question was the three marker on specifications and assumptions. I wasn't clear exactly what it was asking.
Yeah that and the truth table/circuit diagram were very easy.BTW, basically a free 5 marks with the robot question in the interrelationship option.
^That's MC16, and I'm pretty sure B is correct for that.I played a game of redesign tripview on my software paper
MC15 i put B, which I was confident was true, and checked it like 4 times and compared with friends
MC16 I put B, binary search is whatever 2^n > number of values to search. where n is the number of passes required.
To make more sense of that,
2^4 = 16.
An array of 15 elements will take 4 passes.
Wait.. it asked for number of elements. Actually no, I think that's the same thing
Dam, I knew I was doing something wrong with the mantissa, I did the bias the wrong way roundFloating point, the mantissa worked out to be (when adding the hidden bit back) 1.0000... to the base 2.
The exponent was 127. however you had to remove your bias of 127, which made it 0. So the answer was 1*2^0, which is -1 when you factor in the sign bit.
