Examples : Input: N = 1122322 , D = 2 Output: 4 Input: N = 346488 , D = 9 Output: 0 The idea to solve this problem is to keep extracting digits from the number N and check the Write a program to input a number. The program further checks whether the number contains odd number of digits or even number of digits. Scanner; class abc extends Exception{} class slip{ public static void main( String args[]){ A prime number is said to be 'Twisted Prime', if the new number obtained after reversing the digits is also a prime number. Declare a variable evenDigitSum to store the sum value and initialize it with 0. (a) Prime number: (A number is said to be prime, if it is only divisible by 1 and itself) Example: 3,5,7,11 (b) Automorphic number: (Automorphic number is the number which is contained in the last digit(s) of its square. Input : n = 46355364 Output: Reverse of n = 46355364 Palindrome : Yes. Sample Input: 7359 Sum of digits = 24 Number of digits = 4 Given an integer N, write a program that returns true if the given number is a palindrome, else return false. let’s put your knowledge of Java Program to Reverse a Number to the test! Can you solve the following challenge? Challenge: Java Example. Illustration: Case 1: Input : 9 Output : Given number 9 is Neon number Explanation : square of 9=9*9=81; sum of digit of square : 8+1=9(which Given a number x. Right now this is the code I have came up with.
