CHALLENGE: LONGEST PALINDROMIC SUBSTRING 💻⌨️🖱️

Question

Write a code that finds the longest palindromic substring of a given string. If the result is more than one longest palindromic substring, show all (longest). Also show and if there is no palindromic substring.
Note: palindromic substring must contain at least two letters.

Example:
Input: sololearn
Output: olo, length:3
lol, length:3

Input: playground
Output : can't find any palindromic substring

All languages ​​are welcome! 👍

Answer 3

Do you mean that the substring should be symmetric with at least two letters? Did I understand it correctly?

Answer 4

@codasan.com
Palindromic substring means that the substring is the same when read from left to right and from right to left.
For example : b, aa, ana, ceec,...
In this task, palindromic substring need contain at least two letters. That mean that "b" is not valid result.
I hope that helps 😊
