Decreasing for loop in Scala?
scala
Solution
scala>def decrement(start: Int, finish: Int) = {
| for (i <- start to finish by -1)
| println("Current value (decreasing from "+start+" to "+finish+") is "+i);
| }
decrement: (start: Int,finish: Int)Unit
scala> decrement(10, 1)
Current value (decreasing from 10 to 1) is 10
Current value (decreasing from 10 to 1) is 9
Current value (decreasing from 10 to 1) is 8
Current value (decreasing from 10 to 1) is 7
Current value (decreasing from 10 to 1) is 6
Current value (decreasing from 10 to 1) is 5
Current value (decreasing from 10 to 1) is 4
Current value (decreasing from 10 to 1) is 3
Current value (decreasing from 10 to 1) is 2
Current value (decreasing from 10 to 1) is 1
Problem
First day and first attempt at using Scala - so go easy on me! I'm trying to rewrite some old Java code I have which is simply a function which takes two numbers and prints out the numbers from x to y. For example, i have the increment function: ``` def increment(start: Int, finish: Int) = { for (i <- start to finish) { println("Current value (increasing from "+start+" to "+finish+") is "+i) } } ``` However, im struggling writting a corresponding decrement function which will decrease from start to finish? I have read Scala downwards or decreasing for loop? but am still unsure Thank you
