How to find the kth smallest element in the union of two sorted arrays?
...as length respectively. We need to find the k-th smallest element from the union of those two arrays. Here we reasonably assume that (k > 0 && k <= size1 + size2), which implies that A1 and A2 can't be both empty.
First, let's approach this question with a slow O(k) algorithm. The met...
Where to put include statements, header or source?
...ing things like typedefs for integer sizes and a few common structures and unions [e.g.
typedef union {
unsigned long l;
unsigned short lw[2];
unsigned char lb[4];
} U_QUAD;
(Yes, I know I'd be in trouble if I moved to a big-endian architecture, but since my compiler doesn't allow anonymou...

How can I list ALL grants a user received?

Compare two List objects for equality, ignoring order [duplicate]
...here duplicates in either are ignored), you can use:
// check that [(A-B) Union (B-A)] is empty
var areEquivalent = !list1.Except(list2).Union( list2.Except(list1) ).Any();
Using the set operations (Intersect, Union, Except) is more efficient than using methods like Contains. In my opinion, it al...

What are the most common naming conventions in C?
...function names, hardly ever do you see camel case in C;
structs, typedefs, unions, members (of unions and structs) and enum values typically are in lower case (in my experience) rather than the C++/Java/C#/etc convention of making the first letter a capital but I guess it's possible in C too.

Append values to a set in Python
...
You can also use the | operator to concatenate two sets (union in set theory):
>>> my_set = {1}
>>> my_set = my_set | {2}
>>> my_set
{1, 2}
Or a shorter form using |=:
>>> my_set = {1}
>>> my_set |= {2}
>>> my_set
{1, 2}
