Computer Applications
Special words are those words which start and end with the same letter.
Example: EXISTENCE, COMIC, WINDOW
Palindrome words are those words which read the same from left to right and vice-versa.
Example: MALYALAM, MADAM, LEVEL, ROTATOR, CIVIC
All palindromes are special words but all special words are not palindromes.
Write a program to accept a word. Check and display whether the word is a palindrome or only a special word or none of them.
Answer
import java.util.Scanner;
public class KboatSpecialPalindrome
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter a word: ");
String str = in.next();
str = str.toUpperCase();
int len = str.length();
if (str.charAt(0) == str.charAt(len - 1)) {
boolean isPalin = true;
for (int i = 1; i < len / 2; i++) {
if (str.charAt(i) != str.charAt(len - 1 - i)) {
isPalin = false;
break;
}
}
if (isPalin) {
System.out.println("Palindrome");
}
else {
System.out.println("Special");
}
}
else {
System.out.println("Neither Special nor Palindrome");
}
}
}
