How to call erase with a reverse iterator
...Apparently according to the standard [24.4.1/1] the relationship between i.base() and i is:
&*(reverse_iterator(i)) == &*(i - 1)
(from a Dr. Dobbs article):
So you need to apply an offset when getting the base(). Therefore the solution is:
m_CursorStack.erase( --(i.base()) );

How to construct a relative path in Java from two absolute paths (or URLs)?
...necessary checks for you.
String path = "/var/data/stuff/xyz.dat";
String base = "/var/data";
String relative = new File(base).toURI().relativize(new File(path).toURI()).getPath();
// relative == "stuff/xyz.dat"
Please note that for file path there's java.nio.file.Path#relativize since Java 1.7, ...

What's is the difference between include and extend in use case diagram?
...w between use cases is a dependency relationship. I’ll use the terms ‘base’, ‘included’ and ‘extending’ to refer to the use case roles.

A base use case is dependent on the included use case(s); without it/them the base use case is incomplete as the included use case(s) repre...

How do I create a URL shortener?
... MySQL table for example).
For this example, I will use 12510 (125 with a base of 10).
Now you have to convert 12510 to X62 (base 62).
12510 = 2×621 + 1×620 = [2,1]
This requires the use of integer division and modulo. A pseudo-code example:
digits = []
while num > 0
remainder = modulo(n...
Zero-based month numbering [closed]
...e of zero is also popular with pointer arithmetics where you would use one base pointer pointing at some allocated memory, plus a second pointer which would be at an offset from this base pointer. Here, using the value zero makes a lot of sense to point the offset to the base of the memory block. (G...
