2 AnswersMathematics1 decade agoSimple Computer Aided Design?
I need to design something very similar to this: http://images.ctv.ca/archives/CTVNews/img2/2010120...
However, I don't have weeks to learn AutoCAD or 3dsmax or Sketchup (time consuming). Is there any easier solution? I've heard that Adobe Fireworks can be used for these type of design mockups?

4 AnswersEngineering1 decade agoWhat is the worst and best running time of a function?
Sorry for being vague, and the one typo I made probably didn't help my clarity. I'll try not to be brief, so I can explain everything I want to say.
Consider a function with the following characteristic:
Contains no conditionals that depend on the input values. By conditionals I mean any if statement, while loop, for loop, etc. By "depend on the input values" I mean that the conditional somehow compares values on the array (for example). I don't count "for (int x=0;x<n;x++)" to "depend on the input values".
Now, what I meant by "what we were taught in class" was the upper and lower bounds that were taught in "bigoh.pdf" and the upper and lower bounds that were referred to in "complexity.c".
My question is: will the upper and lower bounds be the same for the function I described above?
The reason why I am asking is because I do not understand the thing about n/3*n/3*n/3, that was done in "bigoh.pdf". I asked the TAs during the lab, and all of them spend half an hour trying to figure out why (using a computer, blackboard brainstorming, etc), and couldn't come to a conclusion as to what it meant. So, I assume that it isn't a trivial explanation or something that is really needed in higher level computer science studies. From what you can deduce from what I have said, do I have a good enough understanding of the subject matter (pertaining to big oh, and complexity) to ignore the n/3*n/3*n/3 example?
