Powershell break a long array into a array of array with length of N in one line?

Question

For example, given a list 1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8 and a number 4, it returns a list of list with length of 4, that is (1, 2, 3, 4), (5, 6, 7, 8),

Answer 1

Clear-Host

$s = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18

$count = $s.Length

$split = $count/2

$split --

$b = $s[0..$split]

$split ++

$a = $s[$split..$count]

write-host "first array"

$b

write-host "next array"

$a
