func longestPalindrome(str: String) -> String { var longest = "" for i in 0..<str.characters.count { for j in i+1...str.characters.count { let substring = str[str.index(str.startIndex, offsetBy: i)..<str.index(str.startIndex, offsetBy: j)] if isPalindrome(substring) && substring.characters.count > longest.characters.count { longest = substring } } } return longest;} func isPalindrome(_ str: String) -> Bool { let reversedStr = String(str.characters.reversed()) return str == reversedStr;}🤖 Code Explanation
This code is written in Swift to find the longest palindrome in a given string. The isPalindrome function is used to check if a given string is a palindrome or not.
