int smallest = Array.Sort(sample)[0];

Smallest in source lines or smallest in compiled output?
Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS. "And they, since they Were not the one dead, turned to their affairs" -- Robert Frost

I have assumed a list of integers
List Numbers = new List();
Random r = new Random(10);for (int i = 0; i < 10; i++)
{
Numbers.Add(r.Next(0, 100));
}Numbers.Sort();
var Values = Number.Take(5);Lobster Thermidor aux crevettes with a Mornay sauce, served in a Provençale manner with shallots and aubergines, garnished with truffle pate, brandy and a fried egg on top and Spam - Monty Python Spam Sketch
That's 1 line too many ;)

The funny thing was that when I drafted the question I was thinking about all the smart comments that would be made and so I added "programming" before the word "language". But then thought: Nah - no one would answer with an English sentence. :doh:

What's the smallest code you can come up with to find the n smallest numbers in a random sample of m numbers where n < m. Any language, speed is not an issue.

Is this somehow related to the curious error page I received this morning from Web04? The one featuring ravenous hamsters obviously recovering from a three day methamphetamine/ethanol binge?

In English (again): :D Assume m = A*n + B. If m >> n, then it might be easier to first sort each of the A n-segments and B segment separately. Compare the first element of the A-1 lists and B to the last element of the first A list (or to the last element of the smallest starting A-list) and eliminate all the A segments that are greater than that. Then repeat the process again using n elements selected vertically.

The hamsters have asked for an end to the rumours and baseless allegations of alleged behaviour during certain incidents. The hamsters involved are currently taking some time off to spend more time with their families.

Try this:
#generation of the list
import random
sample = []; n=10; m = 100;rnd = random.Random();
for it in range (1, m): sample.append(rnd.randint(1,n*m))#then
sample.sort()
print sample[:n]
#boom@Chris - When are you planning to start supporting Python in the forum syntax highlighter? :-O [Edit] Not that I'm claiming that my little snippet is beautiful; far from it. I'm still way off being a full-blown Pythonista. But it sure would be nice to have it supported.
Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. In the face of ambiguity, refuse the temptation to guess.
