nodups is a small yet powerful library specialized in working with arrays basically to get unique values and to drop duplicates. But it’s more than just that. Let’s see this in action:.

QUESTION
I have two lists with several columns. Some columns are different, but many are the same and are in different order.
How can I compare List1 to List2, and (for example) delete row 34 of List1 because cell E34 of List1 = H10 of List2
Because of predetermined formats: List1 begins on row 12 (headers in row 11), and List2 begins on row 7 (headers in row6)

- The following will delete all rows in the Destination Worksheet in which a value in a given column is also found in a given column of the Source Worksheet.
- The code (
deleteDupeRows) is 'simplified' by using two functions:refNonEmptyColumnandgetCombinedRange.

I'm running the following command to add multiple keywords to an image:

To prevent duplication when adding new items, specific items can be deleted then added back again in the same command. For example, the following command adds the keywords "one" and "two", ensuring that they are not duplicated if they already existed in the keywords of an image:
exiftool -keywords-=one -keywords+=one -keywords-=two -keywords+=two DIR
The NoDups helper function is used to remove duplicates when they already exist in the file. It isn't used to prevent duplicates from being added in the first place.

ffmpeg.exe -f gdigrab -framerate 30 -i desktop -filter_complex settb=1/1000,setpts=RTCTIME/1000-1500000000000,mpdecimate,split[out][ts];[out]setpts=N/FRAME_RATE/TB[out] -map [out] -vcodec libx264 -pix_fmt yuv420p -preset fast -crf 0 -threads 0 nodups.mkv -map [ts] -f mkvtimestamp_v2 nodups.txt -vsync 0
FFmpeg supports a data format called mkvtimestamp_v2 which stores timestamps as text in millisecond precision. So, in the command above, the input timestamps are first converted to millisecond precision with settb, then setpts is used to assign the wallclock time to each frame. But because the text format has a limited precision, we need to reduce the timestamp. That's done by subtracting 15e11. The after the mpdecimate, we split the result, sending one copy for encoding and one for metadata output.
nodups.txt will look like this
QUESTION
I want to implement a method, that removes duplicates from an ArrayList, by creating a new one without them. I already asked a question about the time complexity of this algorithm, but apparently it doesn't even work. I am pretty sure the error is the equality check but I am not very familiar with Comparators and ArrayLists so any help is appreciated. Here's the code:

QUESTION
I wanted to 'remove' elements in ArrayList by creating a new ArrayList that contains all elements except the duplicates. Duplicates are selected by an comparator and the ordering should be maintained. The algorithm is just iterating over the ArrayList and adding each element that isn't already in the new list. The work is done in a method that is going through the entire ArrayList and checking for equality. Here is the code:

I was asked in a homework assignment to create a method in an existing program, called noDups(), that removes duplicates from a previously sorted array without disrupting the order. The question also states it must be an algorithm with O(N) and make sure no item was moved more than once, no matter how many duplicates there are.
I initially tried a nested for-loop to cycle through and remove duplicates but figured out that was O(N^2). I learned you can solve this problem with a Set. I tried writing the method to take in the long[] (the type of array the program uses) array and convert it to a set, since a set only contains unique values:
...ANSWER
Answered 2017-Nov-02 at 19:57You can't mix primitives and wrappers the way you're trying to -- in particular, Collections.addAll would only accept a Long[], not a long[] in that case.
Accept that you'll need to do some loops to convert back and forth. You'll need to loop over the array and add the elements one by one to the Set, and then create a primitive array and loop over the set to put elements into it.
(Or you could just use Long[] everywhere you're using long[] now, but that'd be inefficient and I'd avoid it in your place.)
QUESTION
I have two .txt files. One contains numbers, and the other one contains filepaths. I want to combine these two files to a .csv. The combination is based on wether the number (from nrs.txt) is in the string of the filepath (nodups.txt).
Now I have the following code for this:
