How can I get a substring from position N to the last char in Ruby?

I'd like to get a substring from a string from position N to the 开发者_StackOverflow中文版end of the string.

What's the way to do it in Ruby?

Just slice the string like:

string[N..-1]

or you can use the size : str[N,str.size-1]

As of Ruby 2.6, you can use endless range syntax for this:

string[N..]

where N is the start index. (No need to specify a -1 for the end index.)
