Given a palindromic number **N**** **in** **the form of string. The task is to find the smallest palindromic number greater than **N** using the same set of digits as in **N**.

**Example 1:**

**Input:**
N =** "**35453"
**Output:**
53435
**Explanation**: Next higher palindromic
number is 53435.

**Example 2:**

Input:N = "33"Output:-1Explanation:Next higher palindromic number does not exist.

**Your Task: **

You don't need to read input or print anything. Your task is to complete the function **nextPalin()** which takes the string **N **as input parameters and returns the answer, else if no such number exists returns "-1".

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

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

**Constraints:**

1 ≤ |N| ≤ 10^{5}
