What is need to create extra variable?

#1

Why are we creating temp? can’t we just head pointer to insert and traverse linked list?

Hello @itsmeshubhamkumar,

The only reason to traverse using a temporary variable instead of head itself is to preserve the address the starting node.

If you’ll traverse using head, then you’ll change the content of head.
The purpose of head pointer(conventionally) is to keep track of the starting of node of the linked list.

Hope, this would help.
Give a like, if you are satisfied.
