经典算法
RFC793 中定义的经典算法是这样的:

Why would adding a method add an ambiguous call, if it wouldn't be involved in the ambiguity
...orm
1: C(params string[]) in its expanded form
2: C<string>(string)
3: C(string, object)
Candidate zero is obviously inapplicable because string is not convertible to string[]. That leaves three.
Of the three, we must determine a unique best method. We do so by making pairwise comparison...

How do I concatenate two lists in Python?
...
You can use the + operator to combine them:
listone = [1,2,3]
listtwo = [4,5,6]
joinedlist = listone + listtwo
Output:
>>> joinedlist
[1,2,3,4,5,6]

Print a list in reverse order with range()?
...parameters. range(start, stop, step)
For example, to generate a list [5,4,3,2,1,0], you can use the following:
range(5, -1, -1)
It may be less intuitive but as the comments mention, this is more efficient and the right usage of range for reversed list.

var list = new List<List<float[]>>();

{
list.Add(locations.GetRange(i, Math.Min(nSize, locations.Count - i)));
}

...n its own).
Note that seq allows floating-point numbers (e.g., seq .5 .25 3.5) but bash's brace expansion only allows integers.
