run an array and compare

RouterOS Scripting
1

good nights,

i have an array with routing marks

array1 (“wan1”,“wan2”,“wan3”,“wan4”,“wan5”,…“wanX”)

and I get an array with the command

:foreach routes in=[/ip route find where comment~"^[a-z]*wan" ] do={
   :set routename ([/ip route get $routes comment]);
   :set array2 ($array2, $routename);
}

the second array sometimes fill with (“wan3”,“wan2”,“wan1”…“wanX”)

the first problem is that the second array is filled in unsorted order, so i need to compare if all the mark on
array1 appears on array2, if not, i will create the route dynamic,
so how i can run both arrays to compare?

thanks
