Given a linked list of size N and a key. The task is to insert the key in the middle of the linked list.
Example 1:
Input:
LinkedList = 1->2->4
key = 3
Output: 1 2 3 4
Explanation: The new element is inserted
after the current middle element in the
linked list.
Example 2:
Input:
LinkedList = 10->20->40->50
key = 30
Output: 10 20 30 40 50
Explanation: The new element is inserted
after the current middle element in the
linked list and Hence, the output is
10 20 30 40 50.
Your Task:
The task is to complete the function insertInMiddle() which takes head reference and element to be inserted as the arguments. The printing is done automatically by the driver code.
