Friday's Coding Challenge

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.

int[] smallest (int[] args, int count) {
int[] copy = java.util.Arrays.copyOf(args,args.length);
java.util.Arrays.sort(copy);
return java.util.Arrays.copyOf(args, count);
}If you don't need it to preserve the original order, then you can drop the first line. This is safe for
count > args.length.

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

Assuming sample is an array of numbers:
int smallest = Array.Sort(sample)[0];

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:

As an accountant I would suggest...
Range("A:A").Select ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Clear ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Add Key:=Range("A1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal With ActiveWorkbook.Worksheets("Sheet1").Sort .SetRange Range("A:A") .Header = xlNo .MatchCase = False .Orientation = xlTopToBottom .SortMethod = xlPinYin .Apply End With Range("C1").Select ActiveCell.FormulaR1C1 = "=RC\[-2\]" Range("C2").Select ActiveCell.FormulaR1C1 = "=COUNTIF(R\[-1\]C\[-2\]:R\[17\]C\[-2\],R\[-1\]C)" Range("C3").SelectThat that is accountants all over!

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.

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?

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.
