What is this O(N*k) sorting algorithm?

由 血红的双手。 提交于 2019-12-19 08:11:16

You take one token off the top of each stack that has tokens, and then add one to each stack in the new set from right to left until your

How can I pull hashtags out of a text column?

由 喜夏-厌秋 提交于 2019-12-11 22:31:04
问题 I have an Excel sheet in which there is a "description" column. The values in this column often contain anywhere from 0-3 tags, all starting with the # symbol. Is there a way to pull all of these tags out in to columns? Perhaps just have 3 blank columns called hashtag 1, 2, 3 and pull them in to each column. It isn't even important that it remove them from the description column while pulling them out. Example of descriptions: "#0034 #lost client lost file" - pull out 0034 and lost "worker

How can I tell what Database format a file (or set of files) was created with (in Delphi)?

由 一个人想着一个人 提交于 2019-12-03 00:23:58
I have a number of data files created by many different programs. Is there a way to determine the database and version of the database that was used to create the data file. For example, I'd like to identify which files are created from Microsoft Access, dBASE, FileMaker, FoxPro, SQLite or others. I really just want to somehow quickly scan the files, and display information about them, including source Database and Version. For reference, I'm using Delphi 2009. First of all, check the file extension. Take a look at the corresponding wikipedia article , or other sites. Then you can guess the
