How can it be decreasing when the question stated show that its increasing, I sort of understand your way of calculating it but I don't think the formula is right.

Can you check to see if this is even a valid question. I got this challenge from someone and I believe there's no way to solve it but have a look. I can't find a perfect bounded above value...I...

I solved it now...thanks.
But please help me with my other Discrete Structures question:

Thanks, I will try to read the link first, attempt the question, and post my findings to see if I'm right...or need additional help.
Thanks so much, also could you take a look at my other thread...

I need help with this question:
Find what a,b,and c is. They must be integer answers.
The equation goes like this:
35a+55b+77c=1
I'm totally confused, I can think of a solution but...

Hey all,
I need help on this problem. Say that x^2 is congruent to 3 (mod 83).
Find the inverse of x (mod 83).
I made a small example case first: (I think all this is wrong now) Please...

I suppose it is.
Does that help any bit?
Basically I believe its asking for a function that is not little o(1) but when you plug in the number 2009 in the new function it will equal to 0 thus...

Ok, I'll give you the whole statement.
This is a two parter question to be treated separate.
Suppose f(x) is a function such that f(x) = O(1).
Can e^{f(x)} = o(1)? Yes or no, provide...

I have another induction question. Here's my work. I think I got it right(except the base case).
Help is greatly appreciated. Thanks in advance.
The question goes as this: Prove using...

Hi,
I have this question that seems trivial to me.
I need to find a function which is not o(1) but where f(2009) = 0 <fyi this is a zero
using the fact that f(x) is a function such that...

Hi,
I wanted to clarify my answer for this question. Please note if I did anything wrong.
The question uses induction.
Prove that for every positive integer n, 4^n+14 congruent 0(mod 6)

So the next step would be this:
P(k): 1+1+2+3+5+8+.........k= (k+2) 1
And the next step would be this:
P(k+1) 1+1+2+3+5+8+.......k+k+1=(k+2)+11 which would simply be:
P(k+1)...

I got this code from the Java Sun site.
Why won't it run?

Thanks! I just put that line in its new location, it works now.
I don't think I could do the other method Xeel said earlier since I didn't learn generics yet.

July 30th, 2009, 06:20 PM
So I put that line above that, and I get 2 errors. Now what?
Here's the new main.

The code is too long to paste here.
It's a linked list example.
No, its not a dumb question...

Why you can't declare a class abstract and final?
Is there some internal rule the system just rejects, or what?
Can somebody provide a sample program demonstrating this?
