Hey, for c++ does any body have a way to compare two arrays? Say one
has the numbers 1-5000, the other has *most* of the numbers from
1-5000, is there a way to display the numbers that are in the 1st
array, but not in the 2nd array? Or load those numbers in a 3rd array?
Thats the simple version...there are a couple other problems: ex:
the 10th value of the 2nd array corresponds to the 12th value of the
first.
- you cant simply make a...

I have to lists, A and B, that may, or may not be equal. If they are not
identical, I want the output to be three new lists, X,Y and Z where X has
all the elements that are in A, but not in B, and Y contains all the
elements that are B but not in A. Z will then have the elements that are
in both A and B.
One way of doing this is of course to iterate throug the lists and compare
each of the element, but is there a more efficient way?

Hello,
I have read many articles about comparing tables, like - loops, delete
queries, appending to temp table with index etc
Problem: 2 tables T1 & T2. Data is suppposed to be the same in both
tables but i need to check that this is so. (Maybe a user deleted a
row in one table only or changed a value in a field!). The tables have
no unique index.

I'd like to compare the values in two different sets to test if any of
the positions in either set share the same value (e.g., if the third
element of each set is an 'a', then the test fails).
I have this:
def test_sets(original_set, trans_letters):
for pair in zip(original_set, trans_letters):
if pair == pair:
return False

Hi,
I have two arrays that are identical and contain 1s and zeros. Only the
ones are valid and I need to know where both arrays have ones in the
same position. I thought logical_and would work but this example proves
otherwise:
>>> a =
>>> b =
>>> Numeric.logical_and(a==6,b==6)
0

This question involves code relying on mmap, and thus
is not maximally portable. Undoubtedly, many will
complain that my question is not topical...
I have two pointers, the first of which is mmapped
to a single page. I want to determine if the second
is on the page. I'd like to do:
#include "platform_appropriate_definition_of_PAGESIZE.h"
int compare1(const char *a, const char *b)

I know that std::vector<boolis specialized to store individual bools
as single bits. I have a question about the comparison operation on a
pair of vector<bool>s.
Is the comparison done bit by bit? That would be slow. In theory it's
possible to just do a bit-wise XOR on all bits and then OR it all
together and compare the single bit right? That would make it O(1)
instead of O(n). What's bad about this method?
Does the size of the...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
