Given a Binary Tree, find vertical sum of the nodes that are in same vertical line. Print all sums through different vertical lines starting from left-most vertical line to right-most vertical line.

**Example 1:**

Input:1 / \ 2 3 / \ / \ 4 5 6 7Output: Explanation:The tree has 5 vertical lines Vertical-Line-1 has only one node 4 => vertical sum is 4 Vertical-Line-2: has only one node 2=> vertical sum is 2 Vertical-Line-3: has three nodes: 1,5,6 => vertical sum is 1+5+6 = 12 Vertical-Line-4: has only one node 3 => vertical sum is 3 Vertical-Line-5: has only one node 7 => vertical sum is 7

**Your Task:**

You don't need to take input. Just complete the function** verticalSum() **that takes **root **node of the tree** **as parameter and returns an array containing the vertical sum of tree from left to right.

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

**Expected Auxiliary Space: **O(N).

**Constraints:**

1<=Number of nodes<=1000
