language agnostic - Adjacent number algorithm grou
 

By which I imply this:

Given the input set of numbers:

1,two,three,four,5 becomes "1-5".

1,Windows 7 Starter Product Key,2,Windows 7 Home Basic,three,microsoft office 2007 sale,5,7,Office 2007 Professional Product Key,9,10,eleven,twelve,14 turns into "1-3, 5,Learning causes structural changes in affected neurons.html, 7, 9-12, 14"

This may be the best I managed to come up with: [C#]

Which feels a bit sloppy to me, so the concern is, is there in some way a lot more readable and/or stylish resolution to this?

public static string[] FormatInts(int[] ints)
{ if (ints == null) throw new ArgumentNullException("ints"); // hey what are you doing? if (ints.Length == 0) return new string[] ""; // practically nothing to process if (ints.Duration == one) return new string[] ints[0].ToString(); // nothing at all to procedure Array.Sort(ints); // need to sort these lil' babies List values = new List(); int lastNumber = ints[0]; // start with the first number int firstNumber = ints[0]; // same as above for (int i = one; i < ints.Length; i++) { int current = ints[i]; int difference = (lastNumber - current ); // compute difference between last number and current number if (difference == -1) // the numbers are adjacent { if (firstNumber == 0) // this is the first of the adjacent numbers firstNumber = lastNumber; else // we're somehow in the middle or at the end of the adjacent number set lastNumber = current; continue; } else { if (firstNumber > 0 && firstNumber != lastNumber) // get ready to print a set of numbers { values.Add(string.Format("0-1", firstNumber, lastNumber)); firstNumber = 0; // reset } else // print a single value { values.Add(string.Format("0",Office Standard 2007 Product Key, lastNumber)); } } lastNumber = current; } if (firstNumber > 0) // if theres anything left, print it out { values.Add(string.Format("0-1", firstNumber, lastNumber)); } return values.ToArray();
}

Интерестно... Вот что вы об этом думаете?
Mожет обсудим одит интерестный , я думаю момент. Точнее небольшую цитату из новостей. Да кстате. Нашла очень даже не плохой видеоонлаин. Главное полезного много и без рекламы!!! Извените, отвлекаюсь, собственно говоря перейдем к самой выдетжке.
