Hi,
I am trying to come up with a way to develop all n-length permutations of a
given list of values. The short function below seems to work, but I can't
help thinking there's a better way. Not being a computer scientist, I find
recursive functions to be frightening and unnatural. I'd appreciate if
anyone can tell me the pythonic idiom to accomplish this.
Thanks for your help,

I have a set of X items, but want permutations of length Y (X > Y). I
am aware of the permutation functions in <algorithm>, but I don't
believe this will do what I want. Is there a way, either through the
STL or some other library to do this, or do I need to write my own
code?

Hi guys,
I want to generate all permutations of a string. I've managed to
generate all cyclic permutations. Please help :)
def permute(string):
l=
l.append(string)
string1 = ''
for i in range(0,len(string)-1,1):
string1 = string + string

Hi,
I'd like to hack a function which returns all possible permutations as lists
(or tuples) of two from a given list. So far, I came up with this solution,
but it turned out to be too slow for the given problem, because the list
passed ("atomlist") can be some 1e5 items long:
def permute(atomlist, size = 2):
"""
returns a list of atoms grouped by two

Greetings,
last week we talked a bit about generating permutations and I told you that
this week will be about combinations. Not true; there's a bit more to tell
about permutations and that's what this Tip Of The Week is about. Maybe later
we'll talk a bit about combinations (if anyone's interested).
The little utility class we implemented last week was able to generate a
next permutation (if any) given a current permutation. But what...

Suppose we are having 3 variables...a,b,c
And we want to print the permutations of these variables...Such
as...abc,acb,bca...all 6 of them...
But we are not supposed to do it mannually...
I want to know that formula by which this can be possible...
Then that program will be ok for nnumber of variables....
Can anyone help me for that?

I have a Dictionary<string, List<string>>, which i have successfully
filled. My problem is I need to create a filter expression using all
possible permutations of its contents.
i.e. the dictionary essentially creates the following array:

I don't know if I'll need pointers for this or not. I wants numbers
10^16. Like a credit card 16 digits of possible 10 numbers, so I guess that
would be 10^16. So I have
int num ;
These are of course declared and not initialized. Now I want to initialize
them all with '\0'. That I'm guessing would involve while ( --). Or maybe
for. Would pointers be involved in this?
With this excercise I would learn working with multi-dimensional

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
