You didn't mention what if you have three times '#'.
e.g. input = "#1234#567#
I assume you want output = "1234#567"
Use the String function "sub" which substitute from the first occurrence only, on the input,
Then reverse the input and use it again (to remove last occurrence)
e.g.:
myString.sub!('#','')
myString.reverse!.sub!('#','').reverse!
This will keep all the '#' chars in between.

What is the most efficient way to drop '#' from the first place and last place if any.

for example:
if input= #hithere# then output = hithere if input = hithere# then output =hithere if input = #hithere then output =hithere if input = hithere then output=hithere
