Exercises in recursion:
What output is produced by the following:
public class Q1
{
public static void main(String args[])
{
methodA(3);
System.out.println();
}
public static void methodA(int n)
{
if (n<1) System.out.print('B');
else
{ methodA(n-1);
System.out.print('R');
}
}
}
What output is produced by the following:
public class Q2
{
public static void main(String args[])
{
methodB(3);
System.out.println();
}
public static void methodB(int n)
{
if (n<1) System.out.print('B');
else
{
System.out.print('R');
methodB(n-1);
}
}
What output is produced by the following:
public class Q3
{
public static void main(String args[])
{
System.out.println(getMysteryValue(3));
}
public static int getMysteryValue(int n)
{
if (n<=1) return 1;
else
{
return getMysteryValue(n-1) + n;
}
}
}
What will the output be if the code in main is replaced by
System.out.println(getMysteryValue(6));
What output is produced by the following:
public class Q5
{
public static void main(String args[])
{
System.out.println("The output is:");
f(35);
System.out.println();
}
public static void f(int number)
{
if (number > 0)
{
f(number/2);
System.out.print(number%2);
}
}
}
What output is produced by the following:
public class Q6
{
public static void main(String args[])
{
System.out.println("The output is:");
bar(11156);
System.out.println();
}
public static void bar(int number)
{
if (number > 0)
{ int d = number%10;
boolean odd=(number/10)%2==1;
bar(number/10);
if(odd)
System.out.print(d/2 + 5);
else System.out.print(d/2);
}
}
}
What output is produced by the following:
public class Q7
{
public static void main(String args[])
{
System.out.println(f(6));
}
public static int f(int n)
{
if (n==1||n==2) return 1;
else return 2*f(n-2) + f(n-1);
}
}
The function in Q7 will produce a series.
Find the first 8 numbers in the series by calculating f(1), f(2), f(3), f(4), f(5), f(6), f(7), f(8)
