Answer:
import java.util.Scanner;
import java.lang.*;
class Main
{
public static void main(String args[])
{
int n;
//For capturing the value of n
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the value of n:");
//The entered value is stored in the var n
n = scanner.nextInt();
int k=1;
printnum(n,k);
}
public static void printnum(int n,int k)
{
if(n%2==0)
{
for(int i=k;i<=n-1;i=i+2)
{
System.out.print(i);
}
System.out.println("");
}
else
{
for(int i=k;i<=n-1;i=i+2)
{
System.out.print(i);
}
System.out.println("");
}
n--;
if(n<=1)
{
System.exit(0);
}
else
{
printnum(n,k+1);
}
}
}

Answer:
Java solution (because only major programming language that has public static methods)
(import java.io.* before hand)
public static boolean s2f(String fileName, String text){
try{
PrintWriter out = new PrintWriter(new File(fileName));
out.println(text);
out.close();
return true;
}
catch(Exception e){
return false;
}
}
Answer:d) Mono-alphabetic substitution rules
Explanation: Poly-alphabetic cipher is the cryptography that is done by using the many alphabets in substitutional way. They are supposed to have a good security because they use cipher text alphabets for the encryption and then decrypts it.
Substitution of the alphabets is done by the rule of the mono-alphabetic substitution rules.Other given options are incorrect because they are not used in the cryptography of the alphabetic cipher. Thus option (d) is the correct answer.
