Problem 43663. Combine the first and last names

MATLAB R2016 provides a rich set of functions to work with string arrays. In this problem, you will be given two string arrays of the first names and last names. Your job is to join the first names with the corresponding last names, and output a new string array.

For example, if the inputs are

firstnames = ["Donald"; "Hillary"];
lastnames = ["Trump"; "Clinton"];

the output should be:

names = ["Donald Trump"; "Hillary Clinton"];
