Day - 48

Assalamu alaykum, everyone! I am going to share the 48th day of my coding challenge! It is late but, I think I came on time.

So, let's start the coding.

1. Problem 5. Longest Palindromic Substring

/*
?* @param {string} s
?* @return {string}
?*/


var longestPalindrome = function (s) {
? if (s.length === 1) return s;


? let longest = "";


? for (let i = 0; i < s.length - 1; i++) {
? ? let odd = palindrome(s, i, i);
? ? let even = palindrome(s, i, i + 1);


? ? longest = longest.length < odd.length ? odd : longest;
? ? longest = longest.length < even.length ? even : longest;
? }


? return longest;
};


function palindrome(s, l, r) {
? while (l >= 0 && r < s.length && s[l] == s[r]) {
? ? l--;
? ? r++;
? }


? return s.slice(l + 1, r);
}        

That's all for today. I am so tired. But it does not have any affects for my challenge. See you!
