concatenation

问题 I want to know if it is possible and if so how I can achieve converting an array of 8 columns and 300+ rows into a sorted, concatenated, one-dimensional array where each row is the concatenation of the contents in the 8 columns. I would also like to achieve this using a single formula. Example: leg | dog | tom | jon | bar | | | | foo | bin | git | hub | bet | far | day | bin | ... would convert into: bar dog jon leg tom bet bin bin day far foo git hub ... I can achieve this for a single row

问题 I have a video file that is 22 seconds long. I want to remove the segment from 10 seconds to 12 seconds. Then return a concatenated video file of seconds 1-10 and 12-22. I want to do this in a single FFmpeg command. This is the easy way Source https://www.labnol.org/internet/useful-ffmpeg-commands/28490/ ffmpeg -i input.mp4 -ss 00:00:00.0 -codec copy -t 10 output_1.mp4 and ffmpeg -i input.mp4 -ss 00:00:12.0 -codec copy -t 10 output_2.mp4 then create an input file with all the source file

问题 I have a sheet that pulls numbers from several different sheets to amalgamate numbers. Each week, a new sheet is added to the source files, all with the same name. I'd like to update the amalgamated sheet by changing one cell instead of many. When the tab is located in the same Google sheet, this is easily done with INDIRECT. Right now, the formula in the amalgamated sheet is: =IMPORTRANGE(M4, "Aug29!$F$2") That formula is on each line to pull from several different sheets: =IMPORTRANGE(M5,

问题 The Problem : I've been searching on here for a while looking for a way to loop through variables named somewhat like variable_1 , variable_2 , ...., variable_n . Basically, I'm asking if there's a way to do that using a loop to achieve variable_i or, more specifically in my case, functionName_i . What I need : I'm trying to loop an objects' array to call different functions which are sequentially-named and parallel to the objects' array ( i.e: obj[ i ]->callback_i( ) ) What I Know :

问题 I need to implement video concatenation in my ASP.NET Web API. I could successfully concatenate some sample videos downloaded from internet using 'FFMpegConverter' Nuget Package . But when I tried concatenating files captured from my mobile and tried opening it, I got the following error. Below is the code snippet I'm using: var ffMpeg = new NReco.VideoConverter.FFMpegConverter(); ffMpeg.ConcatMedia(_fileNames, videoRootPath.mp4, NReco.VideoConverter.Format.mp4, set); These are the Property

问题 For example, there is a function like that: func TestFunc(str string) string { return strings.Trim(str," ") } It runs in the example below: {{ $var := printf "%s%s" "x" "y" }} {{ TestFunc $var }} Is there anyway to concatenate strings with operators in template ? {{ $var := "y" }} {{ TestFunc "x" + $var }} or {{ $var := "y" }} {{ TestFunc "x" + {$var} }} It gives unexpected "+" in operand error. I couldnt find it in documentation (https://golang.org/pkg/text/template/) 回答1: There is not a way

问题 I have the following 2 3D numpy arrays that I want to concatenate. The arrays look like this: a = np.array([[[1,1,1], [2,2,2], [3,3,3]], [["a","a","a"], ["b","b","b"], ["c","c","c"]]]) b = np.array([[[4,4,4], [5,5,5], [6,6,6], [7,7,7], [8,8,8], [9,9,9]], [["d","d","d"], ["e","e","e"], ["f","f","f"], ["g","g","g"], ["h","h","h"], ["i","i","i"]]]) I want to concatenate the two arrays to become one 3D array like: [[['1' '1' '1'] ['2' '2' '2'] ['3' '3' '3'] ['4' '4' '4'] ['5' '5' '5'] ['6' '6' '6

问题 I have been using Allen Browne's ConcatRelated function, and while it works fine when the data comes from a table, but it doesn't work when the data comes from a query. The green 'running query' bar appears for a few seconds, but then when it tries to display the data it shows only one field from the first row, runs very slowly and can take a few minutes to display the first screen of records. I've not managed to leave it long enough to complete the result set, have to shut down Access using
