Programming Challenge – Original Pascal Submission

Earlier this week I set a Programming Challenge using an example from my first year in academia. So far it has attracted 60 or so comments and solutions!

I’m particularly impressed with the range of languages that have been used.

Regular day-to-day offerings in C# are there, C# with LINQ, PowerShell and VBScript. “Vanilla” C, C++, Perl, Ruby and Python aren’t left out; neither are Smalltalk, Haskall, Lisp, clojure, Scala, F#, T-SQL, Informix SQL, SyBase SQL, APL, APL2 and A+. 6502 machine code and Excel are in the submission pot to – extreme diamond plotting!

There are even submissions in Octave and J (references here and here)!

I’ve had offers of solutions in JavaScript and jQuery, hopefully they’ll arrive soon!

I haven’t verified it yet, but here’s one of the J solutions, stunningly terse:

It is written in Iverson’s J programming language.

3 :'(],|.@}:)(|.@}.”_1,.])(AB{~i.Y)(_2<\2#i.Y)}'' ''$~2#Y=.>:y(=i.1:)AB=.a.{~65+i.26′”0

by Tracy Harms

That won me “most cryptic” tweet from Stuart!

Naturally I’m pleased, I wasn’t expecting it to be so popular! Huge thanks to all involved so far!

For the sake of completion, I’ve scanned in the original Pascal submission. Here it is:

Oh dear: notice the scandalous indentation after the FOR loop. Cringe.

If I was to write a C# version of the Pascal code, I might end up with something similar to this:

using System;

namespace diamond
class Program
static void Main(string[] args)
char widest_char;
int next_char, finish_char, wide, range, direction, position, spacelength, loop;

widest_char = Console.ReadKey().KeyChar;

wide = (int)widest_char;
direction = 1;
spacelength = 1;
position = 1;

next_char = 66;
finish_char = 65;

range = 2 * (wide - finish_char);

// Calculate initial left indent
int mid = wide - 65 + 1;

String firstLetter = Char.ToString((char)finish_char);

for (loop = 1; loop < range; loop++) { Console.Write(" ".PadLeft(mid - position)); Console.Write((char)next_char); Console.Write(" ".PadLeft(spacelength)); Console.WriteLine((char)next_char); next_char = next_char + (1 * direction); position = position + (1 * direction); spacelength = spacelength + (2 * direction); // Flip direction when the middle of the diamond is reached if (next_char == wide) direction = -1; } Console.WriteLine(firstLetter); Console.ReadLine(); } } }

Back in 1988, I was reasonably pleased with the Pascal solution. Looking at it now, there are a few things I'd probably change, however hindsight with experience is a wonderful thing.

I can't remember how long it took me to write the Pascal version, probably not very long as I had prototyped the solution using BBC Basic V - a programming language that I had been using since I was 13...some five years before I set eyes on the diamond plotter task! I can't recall exactly, but I'm reasonably sure that the BBC Basic version took me about an hour to get working...

Of course, throwing readability, etc. out of the window, were I thinking about writing a similar solution today in 2009, I might find myself writing something similar to this:

using System;

namespace ConsoleApplication5
class Program
static void Main()
int range = Console.ReadKey().KeyChar - 65;

Console.WriteLine(String.Format("{0}A", "".PadLeft(range)));
int r = 1, dir = 1;
while ((r > 0) && (range>0))
char c = Convert.ToChar(r + 65);
Console.WriteLine(String.Format("{0}{1}{2}{3}", "".PadLeft(range - r),
c, "".PadLeft(r + (r - 1)), c));
if (r == range) dir = -1;
r = r + dir;
Console.WriteLine(String.Format("{0}A", "".PadLeft(range)));


How long did it take me to write a solution today? 30 minutes. 10 minutes of which were spent strangely refactoring for fewer lines of code and terseness. It was interesting writing this version, readability and ability to follow the work-flow came through in the initial version. Then the desire to strip it back to the very basics caught up with me. It's still not perfect, but it does the job. That said, I'm not sure my original Pascal tutor would be hugely happy with it! C'est la vie!

I'll write another post that brings together all the submissions that I've received so far - keep them coming!

052 – Guy Smith Ferrier on Internationali[s|z]ation, VS2008, .net 3.5, C# language features

Tenth the in the Twelve Podcasts of Christmas 2008!

Heroes Happen Here

Stealing a show naming scheme from the NxtGenUG chaps, this is “The One With The Semi-naked man in…”

Luckily it wasn’t our guest, esteemed Internationalisation expert and Microsoft MVP Guy Smith-Ferrier. Andy Westgarth, myself and Guy sat down on the most comfortable seat at this event and chatted about Guy’s session, his user group DotNetDevNet and a host of other things. I decided to edit out the semi-naked man scene in order to keep the flow, however I put it back in near end of the show…every podcast should have a man clad only in boxer shorts, yes?

Despite what it might sound like in this recording, no money changed hands…there will be no cash for questions here, no sir.

I reviewed Guy’s book, .NET Internationalization, over here.

Photos of the event can be found here.

Excel Interop – killing Excel.exe

This posting over at ScottishDevelopers got me thinking, especially since I’ve used Excel and Word from a number of Delphi applications over the last eight years. I have come across this problem in the past (Win32), so I thought it should be fairly easy to chase.

After a bit of research, The Code Project suggested that the Excel process be killed off through code:

Process[] pProcess; 
pProcess = System.Diagnostics.Process.GetProcessesByName("Excel");

Well, that would work, but it might kill off the wrong instance, or kill off the user’s precious ‘expenses’ spreadsheet instead of the one we created.

To help me trace the problem, I used the following code:

using System.Diagnostics;
using System.Runtime.InteropServices;

Excel.Application	excelApp = null;
Excel.Workbook	excelWorkbook = null;
Excel.Sheets	excelSheets = null;
Excel.Worksheet	excelWorksheet = null;
Excel.Workbooks	excelWorkbooks = null;

private void button3_Click(object sender, System.EventArgs e)
  excelApp                 = new Excel.ApplicationClass();
  excelApp.Visible  = true;
  excelWorkbooks   = excelApp.Workbooks;
  excelWorkbook = excelWorkbooks.Add(System.Reflection.Missing.Value);
  excelSheets = excelWorkbook.Worksheets;
  excelWorksheet = (Excel.Worksheet)   excelSheets.get_Item(1);
  excelWorksheet.Cells[1,1] = "42";

private void button4_Click(object sender, System.EventArgs e)
  excelWorkbook.Close (false, System.Reflection.Missing.Value,System.Reflection.Missing.Value) ; 



  excelWorksheet = null;
  excelSheets = null;
  excelWorkbooks = null;
  excelWorkbook = null;
  excelApp = null;


This code creates an Excel application, populates it, then lets us close it. Invoking the button3 code creates it, button4 removes it.

Now, without the calls to the garbage collector, excel.exe hung around if the code behind button3, button4, button3, button4 is invoked.

In the short-term, I would suggest adding the additional calls to the garbage collector (although, and this confirms it, memory reclamation is not guaranteed). It’s time to read up on the garbage collector and COM Interop.

I used Visual Studio 2003 and Office 2003 to test this.
