Kotlin Range with Step Value

Range with Step Value in Kotlin

To define a range with a specific step value in Kotlin, use step function with the range object.

For example, if would like to define an integer range [4, 25] with a step value of 3, use the following syntax.

4..25 step 3

Also, if would like to define an character range ['a', 'z'] with a step value of 5, use the following syntax.

'a'..'z' step 3

    }
}
