I have been tasked on building a code using queues and a class in which you get three options:
- Generates a new number
- Calls on the first number of the queue and takes it out of the main queue(there is an auxiliary queue for that)
- Shows the already called numbers
This is the class created:

I have a program that should simulate the FIFO processor scheduling but the issue with the code is that when it is doing the cicles to simulate process ticks, it changes the value of the table causing an infinite loop. The code is the following:

Answered 2022-Mar-06 at 20:03There is so much wrong with this program its hard to know where to start
- Variable length arrays a non standard c++ , use std::vector
- dont mix c style iO (scanf..) with c++ io (cin...)
- test the return values from things like scanf
But the big issue is this
QUESTION
I've made a GUI using IntelliJ IDEA's form designer, and I have added a JList inside a JScrollPane. The thing is that no matter when or how I add elements to the JList, it doesn't show them. I used the debug tool and I can see that the elements are inside the JList, they just aren't rendered.
I'm currently using a DefaultListModel, but I've tried using Vector and arrays without success. I have also tried using the function updateUI() in the JList, the JScrollPane and the JFrame itself, and the function ensureIndexIsVisible() with the last index of the list in the JList, but nothing.
This form is called from another one and I don't think the code for the main one is needed, so I'll only paste here the code for the faulty form:
...ANSWER
Answered 2022-Jan-24 at 00:51You should call jList.setModel() only once inside the constructor. You are calling it every time you add something to the list.
Try this:

input_text_to_check = str(input()) #Input

#Validation
if m1:
word, association = m1.groups()
word = word.strip()
association = association.strip()
print(repr(word))
print(repr(association))
ANSWER
Answered 2022-Feb-15 at 16:24Based on this explenation of 'Catastrophic Backtracking' I think the issue with your regex is the following:
The thing you try to match with ((?:\w+\s*)+) can be matched in multiple ways. Let's say you use ((?:\w+\s*)+) on the input string abc.
This can be matched in many ways:
- (
aand0whitespaces)(band0whitespaces)(cand0whitespaces) - (
aand0whitespaces)(bcand0whitespaces) - (
aband0whitespaces)(cand0whitespaces)
As long as you only need to match ((?:\w+\s*)+) this works fine. But when you add something else afterwards (like the 10 or so options in your case) regex needs to do some heavy recusion. Have a look at the provided link for a better explanation.
Removing the + after both the \w results in a working regex for the two cases provided:

I'm using Slack Bolt Framework with Javascript and I'm trying to do a http request. The problem is that the code is not waiting the request to be finished even using async/await. It always gives 'undefined'

Here is the code that call the http request function:

I'm benninger in flutter and I need in my TextFormField a filter, if don't have at least one uppercase or lowercase letter, or a number, show error in a text in red with: "Should be have a number", for example.
This is my form (a part, with the relevant parts: textformfields and the voidinitState()):

Answered 2021-Dec-31 at 16:41You can use the validator parameter on TextFormField. Your TextFormField will need to be inside a Form widget for this to work. Pass a key to your Form widget and call formKey.currentState?.validate() in the onChanged callback of your TextFormField.

QUESTION
I am working on a Spring Boot application that take the username and password of an existing user on the system and then generates a JWT token. I copied it from a tutorial and I changed it in order to work with my specific use cases. The logic is pretty clear to me but I have a big doubt about how the user is authenticated on the system. Following I will try to explain you as this is structured and what is my doubt.
The JWT generation token system is composed by two different micro services, that are:
The GET-USER-WS: this microservice simmply use Hibernate\JPA to retrieve the information of a specific user in the system. Basically it contains a controller class calling a service class that itself calla JPA repository in order to retrieve a specific user information:
...ANSWER
Answered 2021-Nov-25 at 12:42Usually, the implementation of AuthenticationManager is a ProviderManager, which will loop through all the configured AuthenticationProviders and try to authenticate using the credentials provided.
One of the AuthenticationProviders, is DaoAuthenticationProvider, which supports a UsernamePasswordAuthenticationToken and uses the UserDetailsService (you have a customUserDetailsService) to retrieve the user and compare the password using the configured PasswordEncoder.
There is a more detailed explanation in the reference docs about the Authentication Architecture.
QUESTION
I got this code which prints a zero matrix given the size (m x n). But i wanna extract a specific value in a specific location of that matrix but i've tried everything i know and it's still not working. Here's my code:
...ANSWER
Answered 2021-Nov-15 at 02:37Your problem comes from the fact that you are calling self.define_matrix()[a - 1][b - 1]) within the get method.
Because of that, no matter which value you insert in your matrix using the set method, what you end up showing is the '0' created upon instantiating the matrix with np.zeros((self.row, self.column), dtype=int).
