LPTHW Exercise 28 CSQ


#1

I did not understand the logic behind common student question 1 under exercise 28.

Also, I did not get the shortcut mentioned in 3. Can someone please explain and give some examples?


#2

Did you try to play with it in the interpreter? Did you do “test” and “test” for example?
The shortcut refers to a shorter way to memorize the boolean expressions, a kind of a hint that makes you click faster if you memorize it instead of memorizing all the expressions.


#3

Yes I did do that and I got ‘test’ . But I do not understand the reasoning behind it. Could someone please explain? I would really appreciate it.


#4

Hi, I gave you some advice in another post so please read that and then come back and augment this post with the information I need. Basically, you have to start doing more work before you ask for questions so that you get used to trying to figure things out on your own.
