Remove trailing char if condition matches

Question

Let's say I have a file with many URLs:

http://foo.com/abc_(Programming_Language)
http://example.com/test)

I'd like to remove the trailing ) for each line in which there is no opening ( using sed and/or grep.

The result file should look like this:

http://foo.com/abc_(Programming_Language)
http://example.com/test

How can I do this?

sed '/(.*)/! s/)$//' file

command

awk '$0 !~ /\(/{gsub(")","",$0);}1' filename

output

http://foo.com/abc_(Programming_Language)
http://example.com/test
