Next Smallest Palindrome | InterviewBit Math | Code Explained

Next Smallest Palindrome is a tricky InterviewBit question. In this video, I cover the code for this question in Python3. We first add one to palindromes to convert them to normal numbers and then we split the cases out into odd and even length cases. We also write some helper functions to make our life simpler. Then, we move onto handling the odd case, using the rules we discussed in the previous video. Finally, we write the case for even and submit.
