Can I get length of array as a value? about rockstar

Got it. Thank you!

I am having a go at some Advent of Code 2021, but it's early days. My style is rather eclectic so far, but I'm learning...

Evaluate your array in a scalar context. For example:

rock x with 1, 2, 3
let y be 0 with x
let z be x without 1
say y
say z

With the second option, when you subtract one from the array, you can even save the knock down operation
