I am confused in head pointer pass by reference or pass by value in the linked list .please clarify it.
Head pointer passed by reference
@rohit_2425
Understand in a simple way, if you pass a variable by reference then you don’t need to update it again after the function call(not to return that thing from function).
But if you pass it by value then just a copy of that variable is passed which has different address in memory location so you have to update the head in that case, after the function call is over.
