Remove First Element In Linked List | FREE DSA Course in JAVA | Lecture 97

In this lecture, we are going to cover remove first operation of linked list which means we have to remove first element from the linked list.
In order to do so, we have to delete the first node and get the head pointed to the next node.
That's the simple operation that we need to cover to remove the first node in linked list.
How we can do it?
It's a simple 3 step operation where we can use a temporary head know as curr.
curr = head
head = head.next
curr.next = null
With this basic operation we will be able to remove the first element & node from the linked list.
Let's see the code in java for the same operation.
