Encryption is a technique of coding messages to maintain their secrecy. A string array of size 'n' where 'n' is greater than 1 and less than 10, stores single sentences (each sentence ends with a full stop) in each row of the array. Write a program to accept the size of the array. Display an appropriate message if the size is not satisfying the given condition. Define a string array of the inputted size and fill it with sentences row-wise. Change the sentence of the odd rows with an encryption of two characters ahead of the original character. Also change the sentence of the even rows by storing the sentence in reverse order. Display the encrypted sentences as per the sample data given below: Test your program on the sample data and some random data. Example 1 : INPUT: n = 4 IT IS CLOUDY. IT MAY RAIN. THE WEATHER IS FINE. IT IS COOL. OUTPUT: KV KU ENQWFA. RAIN MAY IT. VJG TGCVJGT KU HKPG. COOL IS IT. Example 2 : INPUT: n = 13 OUTPUT: INVALID ENTRY import java.util.Scan...

What is a Dudeney Number? A dudeney number is a positive integer such that it's cube root equals its sum of digits. Some examples of Dudeney Numbers Consider the number 512. Sum of digits = 5 + 1 + 2 = 8. Cube root of 512 = 8. So, 512 is a dudeney number. Consider another number 4913. Sum of digits = 4 + 9 + 1 + 3 = 17. Cube root of 4913 = 17. So, 4913 is also a dudeney number. Dudeney Number Program in Java import java.util.Scanner; class Dudeney{     public static void main(String args[]){         Scanner in = new Scanner(System.in);         System.out.print("Enter the number: ");         int num = Integer.parseInt(in.nextLine());         int sum = 0;         for(int i = num; i != 0; i /= 10)             sum += i % 10;         double c = Math.cbrt(num);         if(sum == c)          ...
