Traversing through ranges using progression with a custom step value

Besides doing so for the Iterator instances, progressions implementations for integral types, such as the Int, Long, and Char types, also include the step property. The step value specifies the intervals between the subsequent elements of a range. By default, the step value of a progression is equal to 1. In this recipe, we are going to learn how to traverse a range of alphabet characters with a step value equal to 2. In the result, we want to have every second alphabet letter printed to the console.
