Recursive reverse linked list

how could the (head) change since we pass the head by value?
node* recursive_reverse(node *head)

Hello @mzk1994 we are not changin the head as we are passign it by value but if you can notice then in the video there must be new head which must be storing the head values and we will making change in that only and that will becoime the new head and that will be returned.
