The first argument (file1.csv) would have 3 columns, the second argument (file2.csv) would have 2 columns. The third argument (file3.csv) would have 2 columns.

All files have columns delimited by : (colon).

We need the 2nd column from file1.csv to be removed and concatenated BEFORE file2.csv and this concatenated file should come BESIDE file3.csv. Left is file3.csv, and the LATER columns come from file1.csv and file2.csv.

The delimiter while putting the files BESIDE each other should again be : (colon) 

  Note: - Do not hard-code the filenames. They will be passed in as arguments.
  Assume no headers (to avoid header-non-repetition issues).

  Note: You do not have to print anything, neither you have to make the function call. 
  Just define the function to perform the required operation, return the output & click on check answer.
  Also, note that the function name should exactly be as mentioned above.
