With the reference of this Guru Badge Winning Answer , anyone can explain what is Theta (tight bound), probably, with an example or two.
Omega is lower bound, quite understood, the minimum time an algorithm may take. And we know Big-O is for upper bound...

For example both an upper bound....
Theta requires both Big O and Omega, so that's why it's referred to as a tight bound (it must be both the upper and lower bound).
Big O is the upper bound, while Omega is the lower bound.

New digits of π will typically be CPU-bound, it's just crunching numbers.
It's pretty intuitive:
A program is CPU bound if it would go faster if the CPU were faster, i.e.

I want to find the first item in a sorted vector that has a field less than some value x.
I need to supply a compare function that compares 'x' with the internal value in MyClass but I can't work out the function declaration.
Can't I simply overload '...

The easiest way to make the comparison work is to create a dummy .
For upper_bound and lower_bound.

For 'number-crunching' style applications that use alot of data (reads: "hundreds of MB, but not into GB" ie, it will fit nicely into memory beside the OS), does it make sense to read all your data into memory first before starting processing to avoid...

There is no hard and fast rule that says it will improve performance however .
It makes sense to do things like storing your data in memory if that improves the overall performance .
Your program is as fast as whatever its bottleneck is .

For example:
class MyClass<T extends MyClass2> { // Do stuff... }
Then later:
MyClass<MyClass2> myClass = new MyClass<MyClass2>();
Does this work? My coworker's hunch is no, but I can't find anything to confirm that for me and the documentation...

Super is the opossite, so you can use the bound class too.
That ClassX.isAssignableFrom(T.class)).

Given a reference to a method, is there a way to check whether the method is bound to an object or not? Can you also access the instance that it's bound to?

In either case, the new method's im_class attribute is the class from which .

What is the special case with the foreach/for loop that eliminates bounds checking? Also which bounds checking is it?

}
loop is the one that allows the JIT to safely remove array bounds checks (whether the index is within [0..length-1])
The foreach loop over arrays is equivalent to that standard for loop....
The standard
for(int i = 0; i < array.Length; i++) { .. .

If it's bound to a dataset with the query:
select firstname,lastname,userid from users;
then setting the bound column to userid (3 in the above example) will cause the user ID information to be returned as the listbox value.

Hi guys.
Is it possible to have an UIView with its bounds size different of its frame size?
I'm trying to create an UIView with "{{0,0},{320,367}}" frame and "{{0,15},{320,337}}" bounds but i can't get it done using setBounds() and setFrame().
I got from...

It sounds like you want to add a button below a specific view that was previously... .
The bounds and frame would have the same width and height.
The bounds is at (0,0) while the frame (and center) give the view's position.
Typically:

Are there any lower bounds for floating point types in C? Like there are lower bounds for integral types (int being at least 16 bits)?

In particular, according to the standard any implementation must support a lower-bound of at least 1E-37.
