The StringBuilder one is slightly more efficient and uses
less memory. In practice, it is unlikely to make enough of a
difference to matter either way.

Answer / prasanta khandai
Actually what happens if u add two strings like second one,
then internally it uses the String Builder to call the
append method to add and it converted into the strings again.
so first one is the faster as it appended right ways.

Answer / jimmy dean
The second one is faster.
In the first example the StringBuilder is initialized with
an initial value. Then the append method is ran, adding
another string to 's'. Then the Write method is called,
which calls the ToString() method of 's'.
Total Steps:
1.) Initialize and set initial value
2.) Append
3.) Write
4.) ToString()
In the second example the String is initialized with an
initial value. Then a string is added onto 's'. Then the
Write method is called.
Total Steps:
1.) Initialize and set initial value
2.) Add String to String
3.) Write
Therefore I would say that the second example is faster, and
uses less memory.
