In this challenge, write a program that takes in:

1. a start step,
2. an end step,
3. and a step size.

Show a table that goes from the start step to the end step, in steps of the step size; you do not actually need to show the final end step if the step size does not exactly match.

You should perform input validation:

• do not accept start step less than a lower limit (which your code should specify as a constant) or higher than an upper limit (which your code should also specify).
• You should not allow a step size greater than the difference in steps.
