My C# solution; public static int pageCount(int n, int p) { var books = Enumerable.Range(0, n + 1).Chunk(2); int counter = 0; List counters = [];

  foreach(var pages in books)
  {
    if(pages.Contains(p))
      break;
    counter++;
  }
  counters.Add(counter);
  counter = 0;
  books = books.Reverse();
  foreach(var pages in books)
  {
    if(pages.Contains(p))
      break;
    counter++;
  }
  counters.Add(counter);

  return Enumerable.Min(counters);
}
