How to use shift in ML

Hello !!!

If I have an array and I want to shift the hole array to the right or left.

a[1,2,3,4]
shift right = a[4,1,2,3] shift left = a[2,3,4,1] any idea !!

Thanks !!!

Hey Ba,

I'm not all that fluent with ML anymore however, the following psuedo code should help.

last : rest_without_last

What you want to do cons's the last element into the rest of the elements, but not the last.

Take care,

Mark.
