Please don't answer using links only. In this case, it'd be better to elaborate a bit on each method or to close as a duplicate of one of them.– JJJ ♦Commented Jul 29, 2019 at 21:17

@JJJ, thanks for the comment. I was about to mark it as duplicate. Then, I realized that relevant answers are a bit scattered. Then, compiled previous answers as I couldn't refer many of them as duplicates. I'll pay more attention.– MTSanCommented Jul 30, 2019 at 6:44
