doublearray | JavaScript implementation of Double-Array trie | Natural Language Processing library

Like the question says, I am trying to take the array listed below and go through each number, double the number, and return the new number to the array, and when it's all done, call the method to print the new array. My initial thoughts were that maybe I could go through by row/column and get the number that way, multiply by 2, and then return it, but I'm being told something along the lines of int can't be converted to int[,]. I can not seem to figure out where to go from here.

A function should do only one thing is considered a good practice when writing functions. However, I have a function that is already very minimal, but nevertheless I think it can be further extracted, but I don't know how this can be done.

The following recode() function replaces array values according to a look-up dictionary.

I am trying to convert a python list of lists to a cython multidimensional array. The list has 300,000 elements each element is a list of 10 integers. For this case here created randomly. The way I tried works fine as long as my cython multidimensional array is not bigger then somewhere about [210000][10]. My actual project of course is more complex but I believe if I get this example here to work, the rest is just more of the same.

I have a cython file "array_cy.pyx" with the following content:

I'm trying to solve a simple optimization problem:

I'm building a Spring application to capture data from ~100 websocket clients, then store the data in a queue-like way in a Redis server. The issue is that the server starts to freeze up over time, and eventually the websocket clients disconnect due to host timeouts.

I initially thought the issue was with using Spring Redis Repositories, but the issue persisted once I switched to Redis Templates.

I then thought that the issue was with (de)serialization of Redis objects, and for some time, it was the issue. Through profiling, I found that parsing doubles from strings is slow (when processing thousands per second), so I instead wrote a serialization function to convert double arrays into byte arrays for Redis. This greatly reduced CPU time.

When running the following code snippet, the compiler is attempting to resolve the method isEmpty against a receiver defined in kotlin.collections for reasons I don't fully understand. The method isEmpty is defined within java.util.Optional. If I replace isEmpty with !isPresent, the code works as expected.

as for what i have tried to solve the problem, created multiple adapters with slight code changes i thought might fix the problem, created new button layouts. added toasts to see if the double array i was talking about has even been received by the results page.(it has).these are just some I remember.

Also, I'm a newbie to android. so...

Anyways, I have an image which might be easier to understand - start from the bottom left tab's bottom comments...

android studio screen shot

this is the new screenshot image

this is the code where the problem finally was solved

code added below too.

This is where the problem starts. I think...

I have a third-party C DLL, that came only with its header file as API. I want to be able to call one of its functions. The C header file looks like this:

I am trying to solve the following exercise in C:

"Consider a function dobuleArray() that takes in input an array and a pointer to its size and gives as output the array doubled. Create an array of size 1 to 4 as initial size. Then, start filling the array with 2048 randomly generated integers; each time the array is full, call the doubleArray() ​ function. After each invocation of ​ doubleArray()​ , print again the content of the array"​

I am having issues with an initial size of 3. The program I have written does not work for number greater then 4 and I do not know why, too. Precisely, I get a realloc: invalid next size
