Palindrome Number in Java: Write a program to accept a number from the user and check whether it is a Palindrome number or not. A number is a Palindrome which when reads in reverse order is same as in the right order.
Sample Input: 242
Sample Output: A Palindrome number
Sample Input: 467
Sample Output: Not a Palindrome number
Answer
import java.util.Scanner;
public class KboatPalindromeNumber
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the number: ");
int num = in.nextInt();
int copyNum = num;
int revNum = 0;
while(copyNum != 0) {
int digit = copyNum % 10;
copyNum /= 10;
revNum = revNum * 10 + digit;
}
if (revNum == num)
System.out.println("A Palindrome number");
else
System.out.println("Not a Palindrome number");
}
}

The Greatest Common Divisor (GCD) of two integers is calculated by the continued division method. Divide the larger number by the smaller, the remainder then divides the previous divisor. The process repeats unless the remainder reaches to zero. The last divisor results in GCD.

Sample Output: GCD=5Write a program to find the sum of the given series:
