The code that replaces each letter at a time will be much slower as it
is looking through the entire string for a match for each letter. The
RegEx isn't doing any real work for the pattern match as it is getting
everything. The replace is also not a lot of work as it's just
shifting everything within a certain range (lowercase) to a different
range (uppercase). Ascii shift, basically.
