The Longest Palindromic
Write a function that finds the longest palindromic substring of a given string. Try to be as efficient as possible!
If you find more than one substring, you should return the one that’s closer to the beginning.
Input: A text as a string.
Output: The longest palindromic substring.
Examples:
assert longest_palindromic("abc") == "a"
assert longest_palindromic("abacada") == "aba"
assert longest_palindromic("artrartrt") == "rtrartr"
assert longest_palindromic("aaaaa") == "aaaaa"
Precondition:
1 < |text| ≤ 20
The text contains only ASCII characters.
CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
