The function does the following:

* Takes a `first_name` and `last_name`.
* Converts the first letter of each one to upper case with `title()`.
* <abbr title="Puts them together, as one. With the contents of one after the other.">Concatenates</abbr> them with a space in the middle.

### Edit it { #edit-it }

It's a very simple program.

But now imagine that you were writing it from scratch.

    for (int i = string.length(); i < minLength; i++) {
      sb.append(padChar);
    }
    return sb.toString();
  }

  /**
   * Returns a string consisting of a specific number of concatenated copies of an input string. For
   * example, {@code repeat("hey", 3)} returns the string {@code "heyheyhey"}.
   *
   * @param string any non-null string
