History of AutoCAD

AutoCAD was developed by Michael E. Hall in 1982. In December of the same year, AutoCAD 1.0 was released. By June 1983, the first major upgrade, AutoCAD 2.0, was released, and by 1986, the first major upgrade, AutoCAD 3.0, was released. AutoCAD 3.0 was the first CAD program to include dimensioning and exploded views.

AutoCAD originally ran on the HP-35A and HP-45A desktop personal computer systems. By the time of the release of AutoCAD 4.0 in 1992, AutoCAD was fully native on the Microsoft Windows 3.0 environment. This release heralded the start of AutoCAD’s migration to Microsoft Windows, which has continued to this day, and introduced many new features to AutoCAD, including true raster image capability, the ability to work with metadata (data about the data) such as tags and comments, and the ability to publish a DWF/DWF2 file directly to a web server or web page.

AutoCAD got its name from the software’s initials, which stood for AutoCAD Architecture.

Development is done in the service of the software’s namesake, the AutoCAD Architecture module, which will be introduced in future versions.

AutoCAD Architecture is a three-dimensional (3D) environment that is very advanced. Like other CAD programs, AutoCAD Architecture will allow the user to create a 2D drawing.

Finding all subsets of a given number of set

I’m trying to find all the subsets of a set for a given number of elements.
I have tried to loop through the index 1 to n and then check if the element is in the set using an if statement.
The problem with this is that it is an array and not a set so I’m not sure that will work.
I’m also going to be limited to 1 or 2 arrays so will need to loop through them as well.
Any ideas?


I know this is late, but I just posted the code I came up with and would be glad if someone has a cleaner solution.

use strict;
use warnings;

my $string = shift;
my @array;
my $i = 0;
my @set;

while ( $string =~ /[^$string]+/g ) {
push @array, $string;

for my $i ( 1.. 2 ) {

foreach my $j ( 0.. $i ) {

if ( index( @array, $j ) ) {

print “$j

@set = ();
$set[$i] = 1;
