An empty string is also a palindrome because it “reads” the same forwards and backwards.

A string is said to be a palindrome string if the inverse of that string is identical to the original string. For example radar , level , etc. Likewise, a number that is the inverse of the same number is called a palindrome number. For example 3553, 12321 etc.
A strictly non-palindromic number is an integer n that is not palindromic in any positional number system with a base b in the range 2 ≤ b ≤ n − 2. For example, the number 6 is written as “110” in base 2, “20” in base 3, and “12” in base 4, none of which are palindromes—so 6 is strictly non-palindromic.
Mathematically, yes, a single-letter word is palindromic (also a zero-length word, but let’s not overdo it just yet).
To check whether a string is palindrome or not, we can simply reverse it and compare it to the original string. If remains the same after inversion, the given string is a palindrome. We can see that the filtered string and the reverse filtered string are not the same, so it’s not a valid palindrome.
A palindromic string is a string that stays the same with reversed characters. For example, like ABCBA is “symmetric”..
For a string s, we must specify that at least characters must be appended (insert at the end) to create a string palindrome. Examples: Input : s = “abede” Output : 2 We can create a string palindrome as “abedeba” by adding ba to the end of the string.
The longest palindrome in English is often referred to as tattarrattat, coined by James Joyce in his 1922 Ulysses to imitate the sound of a knock at the door. Try this list of some of the hardest words to spell.
The characters read backwards as well as forwards. Some examples of palindromic words are redivider, deified, civic, radar, level, rotor, kayak, reviver, racecar, madam, and refer.
You are probably familiar with some of the most famous palindromes in the English language, such as “Madam, I’m Adam” and “a nut for a jar of tuna”. How many of these lesser-known, record-breaking palindromes do you know? According to the Guinness Book of World Records, the longest palindromic English word: detarrated.
Therefore, two-character words (or any even-character words) can also be palindromes.
To check if a sentence is palindromic, you need to change all letters to lowercase and then condense the string by removing all spaces and punctuation marks (leaving only a string of lowercase letters) .
A string is said to be a palindrome if it is read backwards or forwards. For e.g. the string above is a palindrome because if we try to read it backwards it’s the same as reading forwards. One of the approaches to checking this is to iterate through the string to the middle of the string and compare a character from front to back.
Create a StringBuffer object by passing the required string as a parameter to the constructor. Reverse the content of the object using the reverse() method. Convert the StringBuffer object to Sting using the toString() method. Now compare the string and the inverse, if true the given string is a palindrome.
