QUESTION
I am looking to find a pair of numbers with a GCD (Greatest Common Denominator) of 1, that the first N terms of the sequence X0, X1, ... XN are all composite.
For my code, for some reason, it gets stuck when i == 15, j == 878, and k == 78. It gets stuck when running is_prime() on the two last items in the list.
...ANSWER
Answered 2021-Jun-15 at 22:27The problem is that your is_prime
function is to slow, instead of checking if every number is a prime inside of your for loop. Why not generate a list of primes, lets say the first 1 million, store them in a list. Then too check if your number is prime, just check if it is inside of the list.

how to update json list / array?

Answered 2021-May-06 at 15:35Since your data seems simple, you can open you data using pandas, do whatever operation you need and then use to_json() function to save again.
Here is the example

QUESTION
I am saving data in my SQL for my school homework
I don't want to update all that data one by one because it is too much would definitely end up finishing it up in the morning.
So I want to automatically update the data when I will modify it
as an example, if the sequence of the data is 1, 2, 3, 4, 5, .... and so on.
If add a data should on the place of 2nd position so the serial number of 2nd will automatically get updated to 3rd and 3rd to fourth and so on.
Hope I defined well 😅😅.
Thanks for your help.... have a nice day :)
...ANSWER
Answered 2021-Jun-15 at 15:23There's no way to insert and automatically push all the other sequence numbers up. You need to do that explicitly.
QUESTION
In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is
Progression: protocol witness for TrainingSetSessionManager.update(object:weight:reps:) in conformance TrainingSetSessionDataManager + 40
This crash points me to the following method:
...ANSWER
Answered 2021-Jun-15 at 13:26While editing my initial question to add more context as Jay proposed I think it found the issue.
What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.
My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.
Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.
The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

QUESTION
I am using WSO2 APIM 2.1.0 and IS 5.3.0
I'm currently trying to create an API that registers a certain user by calling the admin service UserInformationRecoveryService which gives out a custom JSON response if the creation is successful and another response if it is unsuccessful, in which case the user already exists.
So far I have written the in sequence and the out sequence as follows but I am having trouble getting the expected output.(The success response is always seen even when the user already exists. That is, the else block is getting executed in the out sequence.)
In Sequence

QUESTION
I am using the BluetoothLeGatt example from here: https://github.com/android/connectivity-samples/tree/master/BluetoothLeGatt
Assume BLE connection, service and characteristic detection have all happened properly. The following data being sent is value of a characteristic.
From a custom BLE device, I am sending an array of bytes to the smartphone, for example, something line {0x00, 0x01, 0x02, 0x03, 0x04}. In the android program this is received inside the onReceive() function inside BroadcastReceiver mGattUpdateReceiver
in DeviceControlActivity.java
The line
...ANSWER
Answered 2021-Jun-15 at 04:38The example you are using receives the data as a byte array already, but it appends hex representation to the data as string. This is why you get your data in both representations.
You will need to change the example in the file BluetoothLeService.java
on line 149. It is currently reading
intent.putExtra(EXTRA_DATA, new String(data) + "\n" + stringBuilder.toString());
and you would need to change it to
intent.putExtra(EXTRA_DATA, new String(data) + "\n");
if you want to receive only the string representation.

ANSWER
Answered 2021-Jun-15 at 03:42Here's a fairly straightforward way where we test the sign of the lagged difference. If the mid_sum difference sign is the same as the final_sum difference sign, they are "consistent".

Install sequence
You can use sequence like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the sequence component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
