Create a function that computes an approximate value of the mathematical constant e using the following formula:

This function should allow being called in one of the forms:

1. The argument defines the number of items in the formula: e-approx(10).
2. If no argument is passed, the sum contains 100 elements: e-approx().

Print the results for both cases.
