Online service to print an enumeration of numbers
Start: an integer number in the range [-10^18, 10^18]
End: an integer number in the range [-10^18, 10^18]
Step: an integer number in the range [-10^18, 10^18] and not 0
The number of elements in the enumeration must be <= 10^6 and the step should be positive if the start is less than the end, negative otherwise
