Question
Use the following program to do the above questions:
// creating more recursive methods for Lab 7
import java.util.Scanner;
public class Lab7Recursions {
public static void main(String args[]) {
int num1, num2;
String wrd1, wrd2;
Scanner scan = new Scanner(System.in);
System.out.print("Enter an integer for testing summationSquare method: ");
num1 = scan.nextInt();
System.out.println("summationSquare(" + num1+") is equal to "+ summationSquare(num1));
System.out.print("Enter an integer for testing the toBinary method: ");
num1 = scan.nextInt();
System.out.print(num1+"(10) is equal to ");

System.out.println("(2)");
System.out.print("Enter an integer for testing ReverseNum method: ");
num1 = scan.nextInt();
System.out.println("reverseNum("+num1+") is equal to "+ reverseNum(num1));
System.out.print("Enter two words for testing equal method:");

3. Write a few recursive methods to compute some specific values or perform some specific tasks as specified below: i. I 15%) Compute the sum from 12 to n^2 , where n is an input integer. For examples: n-10, summationSquare(10) is equal to 385 n-20, summationSquare(20) is equal to 2870 115%) Print out the binary stream of the value n, where n is an input integer For examples: n-123, 123(10) is equal to 1111011(2) n -234, -234(10 is equal to -1101010(2) i.
