https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/windowed.html maybe this will do what you want? Otherwise consider non-FP solutions, they are easier to read for some kinds of problems.

will check thanx

I guess you can't do a break from it? I've wished I could break out of

List.forEach{}

as well

🙂

could you just not write it as a function and use return to break out of it?

well i am bit new to FP and its declarative nature which I like and so i go to extrme to get used to it and to see "limits"
