The sequence will be generated in the order of the natural numbers. For example, iotaN(0, 5) will yield the sequence 0, 1, 2, 3, 4. The step parameter can be used to increment the sequence by a non-unit amount. For example, iotaN(0, 5, 2) will yield the sequence 0, 2, 4. The step parameter can be negative, which will cause
