Score 43/52

A 43/52 is fine with me. However, I hope that my timing improves and thinking may speed up. Since starting, it took me around two hours to complete the entire thing. For most of the questions I had to use a pen and paper to consider each process, and then really think about it. Seeing how I got a 43/52 with the amount of time I put in, I think that I should really be doing better. I think my main problem is learning to understand large pieces of code(as in putting missing pieces or analyzing certain lines), and I hope that I may focus on that aspect in future tests.

Misinterpreted the 2d array cell, mat[1][3] assigns 4, but there are also other cells.

Selected option (E) would be incorrect as it does not combine the two binary strings together, B actually represents the combined string properly.

Although the first line of “Alex Bob Carl” is proper, the second line doesn’t repeat itself. The second row would set all the names as “Alex” thus D is correct.

The character “!” would actually be printed 6 times, my selected answer of 4 would be correct if it was printed in all of the array.

“On” is not a palindrome thus would not be equal to itself printed backwards. “noon” would be much more fitting as it is a palindrome

Here baboon would actually be inserted at the end of the array list as it begins with the letter ‘b’ and will be added at size-k which is at the end. From there, my order is correct in “bear” following “zebra” etc. I think I had a little trouble understanding the substring and remove commands, and thus need to look at it more in depth.

Just a case of reading the code improperly. Interpreted as printing at index k which would be incorrect.
