Given an IP address, remove leading zeros from the IP address. Note that our IP address here can be a little different. It can have numbers greater than 255. Also, it does not necessarily have 4 numbers. The count can be lesser/more.
Example 1:
Input:
S = "100.020.003.400"
Output: 100.20.3.400
Explanation: The leading zeros are removed
from 20 and 3.
Example 2:
Input: 
S = "100.000.010.0999"
Output: 100.0.10.999
Explanation: The leading zeros are removed
from 0, 10 and 999.
Your Task:
You don't need to read input or print anything. Your task is to complete the function newIPAdd() which takes the string S representing the IP address as input and returns a string representing the resultant IP address. 
Expected Time Complexity: O(|S|).
Expected Auxiliary Space: O(|S|).
Constraints:
1<=|S|<=1000
