Questions I got Wrong:

Question 4: Integers are never coverted to decimal approximations.

Question 6: I didn’t account that procedure one wouldn’t be as efficive as procedure two, but it would eventually get to the goal.

Question 16: Index must be subtracted by one!

Question 22: I got tricked. Spin = 1 means a 1 in 8 chance, and move 1 space should have a 6/8 chance.

Question 23: I overthought this question WAY TOO MUCH. The requirement for available to be true is just for the two conditions to be true.

Question 28: These questions are confusing for me. I don’t really understand them too well, so I just guessed that all of the code segments worked. The correct answer was 1 and 3; 2 doesn’t work because temp becoming alpha and alpha becoming temp don’t really do anything and temp cannot represent both alpha and beta.

Question 32: I got this one wrong because I thought you could do Sum - Min then simply do finalgrade divided by length. However the problem with this is that length is still the four scores and will divide by 4 rather than 3. D is the correct answer, as it’s the exact same code except theres a -1 after LENGTH which corrects the issue of C.

Question 37: This question took a lot of thinking for me, it was difficult to conceptualize. I saw the answer was to draw the line first then subtract two from endY and discovered it worked, I was overwhelmed with the other three and didn’t notice that A was the right answer.

Question 54: I thought the code worked, but the correct answer was to change line 5 to APPEND (newList, number) because the current code would put reverse the original order because it would be ordered from greatest to least.

Question 58: This question was confusing to me, as I had blindsighted the fact that if all of the parameters were different, the code WOULD work as intended, even though it returns a false value. The answer is C, which messes up the intended purpose because the parameters in AnyPairs already meets criteria.

  • Certificate Authority: an organization that acts to valudate identities and bind then to cryptographic key pairs with digital certificates.
