Given a doubly-linked list, a position **p,** and an integer **x.** The task is to add a new node with value **x** at the position just after **p ^{th}** node in the doubly linked list.

**Example 1:**

**Input:
**LinkedList: 2<->4<->5
p = 2, x = 6
**Output: **2 4 5 6**
Explanation: **p = 2, and x = 6. So, 6 is
inserted after p, i.e, at position 3
(0-based indexing).

**Example 2:**

**Input:
**LinkedList: 1<->2<->3<->4
p = 0, x = 44
**Output: **1 44 2 3 4**
Explanation: **p = 0, and x = 44 . So, 44
is inserted after p, i.e, at position 1
(0-based indexing).

**Your Task:**

The task is to complete the function **addNode**() which head reference, position and data to be inserted as the arguments, with no return type.

**Expected Time Complexity** : O(N)

**Expected Auxilliary Space** : O(1)

**Constraints:**

1 <= N <= 10^{4}

0 <= p < N
