Fix the problem of using '+' and '+=' operators to concatenate strings a in
a loop.
The method is building a String using concatenation in a loop.
In each iteration, the String is converted to a StringBuilder, appended to,
and converted back to a String.
This can lead to a cost quadratic in the number of iterations, as the
growing string is recopied in each iteration.
Better performance can be obtained by using a StringBuilder explicitly.
