What I Learned
If there is anything I took away from this quiz is the breadth and depth of computer science—something that isn’t inclusive just to coding but to networking, cybersecurity, algorithms, and much much more.
Weaknesses
Questions involving algorithmic coding were often a challenge and made up the bulk of the questions I got wrong.
Questions I got Wrong
-
Q30:
Need to be more observant with how many times a function is called
-
Q31:
Need to trace each step to the end
-
Q43:
Polynomial algorithms run in a reasonable amount of time?
-
Q44:
Dumb mistake; 2^4 = 16 possible integers so anything at or below won’t cause an overflow error
-
Q52:
Different order; same result
-
Q56:
Need to carefully count the steps
-
Q57:
Substrings confusion (need practice on that)
