Reversing | Dump of scripts i have used/written while reversing binaries | Reverse Engineering library

I want to write a program for reversing a number. For reversing a number like 2300 to 32 so that the ending zeros are not printed, I found this method:

My main objective is to return if all elements, int[ ], of a 2D Array ,int[ ][ ], are present in another 2D Array.

I already tried to use Arrays.deepEquals() but in this case, the order of the elements would matter and that's not the purpose.

• Int[ ][ ] arrays wouldn't be longer than 15, for example.
• Int[ ][ ] arrays have always the same length.
• Int[ ][ ] arrays order doesn't matter, but Int[ ] arrays does.
• Int[ ] arrays would always be a pair.

Thanks for reading this. I'm trying to modify a sketch.js provided by the author of this pixel sorting tutorial.

I wonder what's the best way to store the original location of each pixel in an additional texture so as to enable the image to be sorted back to the original?

So far, my goal was to put 2 conditional statements within the draw function such that at a certain point in time (or number of iterations) the pixels start bubble-sorting back to the original image, and only then sort back up again.

Things might be correct

1. To change the sign of the comparison (i.e., from greater to minus)
2. To copy .loadPixels() and .updatePixels() in both statements.

Things I'm not so sure about

1. Reversing the for loop in the else statement
2. Changing the pixel indexing from (j, i + 1) to (j, i - 1)

Things I've not figured out yet

1. A way to sort back up again once the original image gets recomposed

I am trying to extract a number from a string. The string is a filename, will be variable in its contents, but will end with a space followed by a number.

So strings like a b 1212, a 1212. I am not sure if filenames ever end up with a whitespace at the beginning, but something like 1212 should not produce a match.

I am using so far

This question applies to any particular programming language.

Let us imagine I have a function that converts a data structure to a string of hex.

FIXED: While upgrading Ubuntu 21.04 to 21.10 firefox (previously installed with apt) got removed and installed with the snap-version. Reversing (uninstalling the snap version & reinstalling with apt) this fixed my issue.

I should've investigated after I had to reset firefox to be the default browser after the dist-upgrade again.

When trying to create a Firefox Webdriver with Selenium for Python I get greeted with the following: "Your Firefox profile cannot be loaded It may be missing or inaccessible." And after clicking 'ok' the following stack trace appears:

I am trying to figure out how to reverse for example,grades{1, 2, 3, 4, 5, 6} starting at the third element.

I know for lists we cannot do (grades.begin() + 2) to obtain the position, but I'm not sure how to go about it. This is what I have so far, where I'm just reversing the entire list:

I am new to python and doing a test program that replaces all the letters in a given text with signs.

I'm working on a pyspark routine to interpolate the missing values in a configuration table.

Imagine a table of configuration values that go from 0 to 50,000. The user specifies a few data points in between (say at 0, 50, 100, 500, 2000, 500000) and we interpolate the remainder. My solution mostly follows this blog post quite closely, except I'm not using any UDFs.

In troubleshooting the performance of this (takes ~3 minutes) I found that one particular window function is taking all of the time, and everything else I'm doing takes mere seconds.

Here is the main area of interest - where I use window functions to fill in the previous and next user-supplied configuration values:
