Nevermind.

[SoccerDude28]

Okay take this example. You have 3 numbers: X, Y and Z. (X, Y and Z can be any 3 numbers at random)

How would you go about finding which one is the smallest. Forget about programming for now, just use your common sense logic.

[SakSquash]

Well...I would look at it...see which one is the smallest..and say yup, that's the smallest.

I think i'm missing your point?

What SoccerDude meant is: how to find the smallest number if you can compare only two at the time? (because the "min" function gives you the smaller of two, not three)

So, suppose you have three rocks and a scale such as this one (doesn't show you the weight, only allows to compare two things). How would you proceed to find the lightest one?

In computers you can only compare two elements to each other at one point. To find out if something is smaller than another you use a comparison operator (namely the "<" or ">" signs).

so to compare if X is smaller than Y, you would say if(X<Y).

So let's go back to our small example. You have 3 numbers hidden from you X, Y and Z. They can contain any number. You can compare two of them at a time, using the if operator like the example above. How do you go about finding the minimum of the 3 numbers. You can only compare two of them together at one point, and their contents is unknown to you before you run the program.

I dunno? Something like X<Y, X<Z, Y<Z?

Okay suppose you have 4 elements W, X, Y and Z, how would you find the minimum? EDIT: And you can also only compare 2 at a time.

With three variables you only need to test twice. Once you know that X is smaller than Y and Z, you know it's the smallest.
For example:
x = 4
y = 5
z = 6

compare x, y // result x, compare it to the next
compare x, z // result x, x is the smallest

x = 5
y = 4
z = 6

compare x, y // result y
compare y, z // result y

x = 5
y = 6
z = 4

compare x, y // result x
compare x, z // result z

For just three you're looking at something like this, in pseudo code:
if (x<y)
result=x
else
result=y

if (result>z)
result=z

any more variables and you should be thinking about loops, on the same principle, just keep passing the smallest number to the next in the list, comparing, then passing that along, the number at the end is the smallest.

That's what I was trying to get to. I wanted Saksquash to think about a little though

If he uses that logic with three variables, then the chances are he'll use them with four. He had a stab at it, didn't get it, I gave him an example to help him. I don't see the point in asking the same question twice.

Then, if I might be blunt, what the heck are you doing taking programming classes? I mean, coding is full of math, or at least related ways of thinking.

The course is web design...as in html...I didn't know i'd be doing java.

[Jeysie]

So... somehow you never expected a web design course to consist of learning web technologies?

Peace & Luv, Liz

[SakSquash]

Shut the **** up.

No, he's right. I wouldn't neccesarily expect an HTML course to incorporate Javascript. I think it's good that it does, because it's a useful technology, but it's not something I think is a given in an intro to HTML course.

Heh. Well, I have to admit I'm now curious about why he's taking the course. Because even if an Intro to HTML course didn't have javascript stuff, if you were going to be "serious" about web designing, you'd have to take classes on other web technologies eventually anyway, I would think.

Which is one reason why I never bothered getting serious about webmastering even though I enjoy it... trying to figure out most programming concepts (i.e. anything beyond HTML and CSS) gives me a headache.
