What is the best optimal way of finding whether any element is repeated in a given array?
Answer Snippets (Read the full thread at stackoverflow):
If it is sorted, you can just look one to the left and one to the right... .
You need to check each element, usually using a hashtable .
In general, it is an O(n) problem.
Put the elements in a hashtable, doing value equality comparisons on any collisions .

I have two vectors u and v. Is there a way of finding a quaternion representing the rotation from u to v?

One rotation from u to v would be a pi / 2 rotation around the z... .
Consider the case, for example, where u = <1, 0, 0> and v = <0, 1, 0> .
The problem as stated is not well-defined: there is not a unique rotation for a given pair of vectors .

I was curious as to how does one go about finding undocumented APIs in Windows.
I know the risks involved in using them but this question is focused towards finding them and not whether to use them or not.

Is there an easy way of finding of finding the neighbours (that is, the eight elements around an element) of an element in a two-dimensional array? Short of just subtracting and adding to the index in different combinations, like this:

For a more general-purpose.
Convert rows to integers and use bitwise operations to find the ones you want.

I need to write a regular expression in ruby for finding a string like 'some' and then replace it with say 'xyz.some'. How do I go about it?

You find 'some' (or anything other) and then you can use \0 in replace string (watch for quoting, you" str_to_find = "the" a.gsub(/(#{str_to_find})/, 'xyz.\1') # => "xyz.the quick brown fox jumped.
