Problem 649. Return the first and last character of a string

Created by @bmtran (Bryant Tran)

Solve Later

Return the first and last character of a string, concatenated together. If there is only one character in the string, the function should give that character back twice since it is both the first and last character of the string.

Example:

   stringfirstandlast('boring example') = 'be'

Well, I guess my understanding that string is defined using (" " , i.e. double quotations) is incorrect. I thought class string was formally distinguished from char (defined using ' ', i.e. single quotes). I should have looked at the test-suite.

Only need:
out = x([1 end])
This is legal even if length(x) == 1, because in that case, x(1) == x(end)
