alright gufmn, just you and me...

[inkedmn]

I hereby challenge gufmn to a python duel TO THE DEATH. :)

here's the deal...

gufmn and i recently took a test in our java class. the details of the test are here (http://staffwww.fullcoll.edu/brippe/cis226/tests/Test1.htm)

gufmn (should he choose to accept this challenge) and i will be writing exactly the same program in python. it must do EVERYTHING outlined in the test description above. the winner will be determined by the cleanliness and efficiency of their code.

now, an impartial third party will have to judge this duel. who will accept this challenge?

gufmn, DO YOU ACCEPT?

:)

[gufmn]

Is there a time frame for completion? I'm kinda buisy right now.

[inkedmn]

i'd say by Sunday at midnight.

if you'd like more time, that's cool.

[gufmn]

You're on! In time frame we agreed upon through IM.

/me grabs glove, smacks inkedmn across the face and proceeds to walk 10 paces.

oo We oo We oooo.....(The sun begins to set)

[GnuVince]

Inkedmn asked me to be judge. I accept.

I just want to mention that I've got the solution implemented in Python and Ruby ;)

[ChefNinja]

interesting :D

[Strike]

Can I judge?

[GnuVince]

Strike: No. I am the judge. You can write an entry though and email it to me and I'll give you a score.

[GnuVince]

Oh by the way guys, you can send me many versions. I will correct the last one recieved before the deadline.

[kmj]

If Gnuvince is the judge you'll get bonus points if you write it in frenchie!!! :D

thanks for offering, man :)

[Strike]

Oh I thought it was going to be a panel of judges, not just a single judge. (NOTE: not just because I want to judge do I say this, but that's a generally better idea anyway just so you can get several different perspectives and win on aggregate score)

[inkedmn]

hmm...

not a bad idea actually. i'll have to see how gufmn feels about it...

gufmn?

[jemfinch]

I can judge too, if you like.

Jeremy

[gufmn]

I don't care who judges.

inkedmn: if you think it best to have multiple judges, that's cool with me. In the mean time, I'm just going to send my code to Vince. Should it be decided that more judges is the way to go, I'll send it to them as well.

[GnuVince]

I'll wait to see inkedmn's entry before I decide if I want advise from Strike.

By the way, gufmn's entry does what is expected.

[GnuVince]

Winner: inkedmn.

I declare inkedmn the winner of the 'inkedmn v. gufmn' duel. For one, ink's code is generally easier to read than guf's. Since, this was a Python contest and that Python is an OO language, inkedmn gets more points for having a OO design. gufmn loses a point for using a global variable. By the way gufmn, you don't need to put int() to declare an integer variable. The output on ink's program was clearer than guf's.

ink's program was also faster (printing 12 size 50 triangles):


You made 12 triangles!
python2.2 ink.py 0.04s user 0.01s system 0% cpu 20.662 total

...

Total number of triangles printed: 12

Goodbye...
python2.2 gufmn.py 0.14s user 0.02s system 0% cpu 19.236 total


This is probably due to the fact that ink used 'for' loops and guf used
'while' loops to print the triangles.

I accord a coolness point to gufmn's program for not having a main loop,
but for using recursion instead. Inkedmn also gets a coolness point for
managing plurals in his program.

Both player used meaniful variable and function names making it easier
for me to understand their programs. Also, major point to gufmn for using 4-space tabs (thus respecting the Python coding guide lines!) unlike inkedmn who still uses 8-space tabs. Good job on using the 'in' operator for the "Draw again" question too.


Big phat l33t congratulations to both participants! If other members have version (in Python or other languages), you are invited to post them.

By the way, scanez you may not cry because inkedmn won ;)

Here are my versions; one in Python, the other in Ruby:

for x in xrange(1, size+1):
print "*"*x

for x in xrange(size-1, 0, -1):

print "Thank you for playing the triangle game"
print "You created %d triangles" % number_of_triangles



Ruby:

#!/usr/bin/env ruby

def plural?(n)
case n
when -1..1 then ""
else "s"
end
end

def draw_triangle(size)
# Draw first half

sniff sniff

inkedmn: I'm so proud of you...

/me wipes a tear away

Sorry GnuVince, couldn't hold back ;)

[Strike]

Big fat minus points for no comments or docstrings in each :P

[gufmn]

Congrats ink!
You know I never expected to win.
Hmmm.....but I bet you did.

inkedmn's ego++

I hope you feel better ;)

[inkedmn]

JERK!

er, thanks :)

nice job guf

[Dru Lee Parsec]

Hey Guys, How much time were you given to write the original Java code in class?

[gufmn]

About 2-1/2 hours total. But I lost about an hour because the computer I was using was effed. :)

Plus, I had to re-boot about an hour into it, due to the effed computer, and as it turns out, the lab machines delete all files created by students when it is shut off. So I had fun.

btw: the instructor was the one who suggested the re-boot.

[Dru Lee Parsec]

20 minutes, all 5 task complete:


import java.awt.*;

public class Triangle {

private static EasyIn easy = new EasyIn();
private static int count = 0;

public static void main(String[] args)
{
do {
doLogicLoop();
count++;
} while (goAgain());

System.out.println("Thank you for playing the triangle game");
System.out.println("You created " + count + " triangles");
}

private static boolean goAgain() {
boolean shouldReturn = false;
boolean done = false;
do {
System.out.println("Would you like to do another triangle?");
System.out.println("(Y)es (N)o");
System.out.flush();
String shouldGo = "" + easy.readChar();
if (shouldGo.equalsIgnoreCase("Y")) {
shouldReturn = true;
done = true;
}
else if (shouldGo.equalsIgnoreCase("N")) {
shouldReturn = false;
done = true;
}

if (!done) {
System.out.print("Error: ");
}
} while (!done);
return shouldReturn;
}

private static void doLogicLoop(){
System.out.println("Please type the size of the triangle:");
System.out.flush();
int x = easy.readInt();
if ((x< 1) || (x> 50)) {
System.out.println("Error: Invalid triangle size");
count--;
}
else {
// x in in proper range so print it
// Print the triangle
// This is the first half of the triangle
for (int h = 0; h<x;h++ ) {
for (int i = 0;i <= h;i++ ) {
System.out.print("*");
}
System.out.println("");
}

// this is the 2nd half
for (int j = x-1; j>0;j-- ) {
for (int k = 0;k <j;k++ ) {
System.out.print("*");
}
System.out.println("");
}

}
}
}

^^ showoff

[Dru Lee Parsec]

yup :D

[kmj]

Dru: now do it in python. :p

[Kastaka]

Hey, I know I'm really really late, and that the contest wasn't really open, and that I'm not using python, but C++, but I figured what the hell. Maybe someone would be interested. Here is mine in C++. The comments are a little weird, I don't remember making them...

#include <iostream>
#include <ctype.h>
using namespace std;

void DrawTri(int x, int start = 1) // recursive function to draw triangles
{
int ast = 0;

do {
ast++; // increment count of *'s on current line
cout << '*'; // output *
} while(ast < start); // outputs * till limit

cout << endl; // next line

if(start < x) DrawTri(x, start+1); // recursion call
else return; // returns if limit is reached

ast = 0; // reset * count

/* this forms the rear slope of the triangle and will only
execute if the number of asterisks on the line, isn't
the limit */
do {
ast++; // increment * count on line
cout << '*'; // output *
} while(ast < start); //output * till limit

cout << endl;
}

int main()
{
int x, numtris = 0;
char choice;

do { // loop while user chooses to make more triangles(user chooses 'y')
do {
cout << "Triangle size(1 - 50): "; // prompt user for triangle size
cin >> x;
if(x < 1 || x > 50) cout << "Error: Invalid triangle size(1 - 50)\n";
} while(x < 1 || x > 50); // loop until accepted value is received

DrawTri(x); // call the function which draws the triangle
numtris++; // count number of triangles drawn
do { // loop while choice is invalid
cout << "\nDraw another triangle? (Y)es/(N)o: "; // prompt user if they wish to draw another triangle
cin >> choice;

if(tolower(choice) != 'n' && tolower(choice) != 'y')
cout << "Error: Choices are (Y)es or (N)o"; // output error if input is unacceptable
} while(tolower(choice) != 'n' && tolower(choice) != 'y');
} while(tolower(choice) != 'n');

cout << "Number of triangles made is: " << numtris; // output number of triangles drawn
