A palindromic number is a number that reads the same forward and backward. 101, 4 and 6666 are palindromic numbers while 10, 564 and 15452 are not.
You will be given a String n representing a positive integer. Determine the smallest palindromic integer strictly greater than n, and return it as a String with no leading zeroes.
|-||No positive multiple of 10 is a palindromic number.|
|-||n will contain between 1 and 50 characters, inclusive.|
|-||Each character of n will be a digit ('0'-'9').|
|-||The first character of n will not be zero ('0').|
