...verse(s) {
s = s.split('');

tmp = s[len - i - 1];
s[len - i - 1] = s[i];
s[i] = tmp;
}

What is the purpose of the “final” keyword in C++11 for functions?
...truct D : public C { /* cannot override foo */ };
Then the final puts a 'floor' on how much overriding can be done. Other classes can extend A and B and override their foo, but it a class extends C then it is not allowed.
So it probably doesn't make sense to make the 'top-level' foo final, but it...
What's the strangest corner case you've seen in C# or .NET? [closed]
...re:
i1 == 14
i2 == 13
It's always better to call Math.Ceiling() or Math.Floor() (or Math.Round with MidpointRounding that meets our requirements)
int i1 = Convert.ToInt32( Math.Ceiling(d) );
int i2 = (int) Math.Ceiling(d);
