Q:

pattern regex for apache rewrite

I have a bunch of URLs counting to thousands i need to redirect and there are thre main patterns in URL
first pattern
There is a dash - starting the title url and want to remove that dash 
e..g
www.example.com/buzz/news/the-written--malice-of-rdicile www.example.com/buzz/news/the-written-malice-of-rdicile

www.example.com/break/news/5-kids--were-found-rigmaroling-armed  www.example.com/break/news/5-kids-were-found-rigmaroling-armed

second pattern
There are two dashes -- in between urls that need to be changed to just one dash - 
e..g
www.example.com/buzz/news/-the-written-malice-of-rdicile www.example.com/buzz/news/the-written-malice-of-rdicile

www.example.com/break/news/-5-kids-were-found-rigmaroling-armed  www.example.com/break/news/5-kids-were-found-rigmaroling-armed

third pattern
There is a dash - ending the title url and want to remove that dash 
e..g
www.example.com/buzz/news/the-written-malice-of-rdicile- www.example.com/buzz/news/the-written-malice-of-rdicile

www.example.com/break/news/5-kids-were-found-rigmaroling-armed-  www.example.com/break/news/5-kids-were-found-rigmaroling-armed

fourth pattern
There is combination of starting dash, double dashes and ending dash in the url and want to remove the starting dash and ending dash and change double dash to single dash
e..g
www.example.com/buzz/news/-the-written--malice-of-rdicile- www.example.com/buzz/news/the-written-malice-of-rdicile

www.example.com/break/news/-5-kids-were-found--rigmaroling-armed-  www.example.com/break/news/5-kids-were-found-rigmaroling-armed

www.example.com/break/news/-5-kids-were-found-rigmaroling-armed-  www.example.com/break/news/5-kids-were-found-rigmaroling-armed

There are about 5000 lines of these patterns, so looking for a way to use regex or other means to be able to run through all 5000ish lines and apply the apache rewrite to the URLs
Help will be VERY much appreciated. 
Thank you in advance
P.S will continue to edit to make question clearer; any question?  please ask me. 
So altogether, it looks like this
LEFT will be the URL to be redirected and RIGHT will the the final URL users need to be on

A:

It ended up that i had matching source and destination URLs and did not need to use regex to simplify or do any optimization. 
So just did it line by line, so 5000ish line redirects..yes i know
