Text info can be read from varied sources and is often unsuitable for direct processing or usage by core functions. This necessitates methods for post-processing and data-fixing. In this tutorial, we'll learn how to remove flanking whitespace and newline from strings.

• String.chomp(separator=$/): Returns a new string with the given separator removed from the end of the string (if present). If $/ has not been changed from the default Ruby record separator, then chomp also removes carriage return characters (that is, it will remove \n, \r, and \r\n).

> "Hello World!  \r\n".chomp
"Hello World!  "
> "Hello World!".chomp("orld!")
"Hello W"
> "hello \n there".chomp
"hello \n there"

• String.strip - Returns a new string with the leading and trailing whitespace removed.

> "    hello    ".strip
"hello"
> "\tgoodbye\r\n".strip
"goodbye"

• String.chop - Returns a new string with the last character removed. Note that carriage returns (\n, \r\n) are treated as single character and, in the case they are not present, a character from the string will be removed.

> "string\n".chop
"string"
> "string".chop
"strin"

In this challenge, your task is to code a process_text method, which takes an array of strings as input and returns a single joined string with all flanking whitespace and new lines removed. Each string has to be separated by a single space.

> process_text(["Hi, \n", " Are you having fun?    "])
"Hi, Are you having fun?"
