Create a list of unique characters by iterating through the hash table.
Calculate the length of the string using the built-in length function.
Return the frequency, length and list of unique characters as an array of strings.
To check if a string is palindrome or not.
Compare the first and last characters of the string and continue towards the middle until all characters have been compared.
If all characters match, the string is a palindrome.
If any characters do not match, the string is not a palindrome.
