**Background**

A simple mathematical formula for e is

"""

where n is allowed to go to infinity. This can actually yield very accurate approximations of e using relatively small values of n.

**Output**

Output the approximations of e generated by the above formula for the values
of n from 0 to 9. The beginning of your output should appear similar to that
shown below.

**Example **

**Output**

n e - ----------- 0 1 1 2 2 2.5 3 2.666666667 4 2.708333333
