Java: Towers of Hanoi Variant

Consider the following variant of the towers of Hanoi problem, There are 2n discs of increasing size stored on the three poles. Initially all of the discs with odd size (1, 3,..., 2n-1) are piled on the left pole from top to bottom in increasing order of size; all of the discs with even size (2, 4, ..., 2n) are piled on the right pole. Write a program to provide instructions for moving the odd discs to the right pole and the even discs to the left pole, obeying the same rules as for towers of Hanoi (The towers of Hanoi provided below)

public class TowersOfHanoi {

// print out instructions for moving n discs to
// the left (if left is true) or right (if left is false)
public static void moves(int n, boolean left) {
if (n == 0) return;
moves(n-1, !left);
if (left) StdOut. println(n + " left");
else StdOut. println(n + " right");
moves(n-1, !left);
}

public static void main(String[] args) {
int n = Integer. parseInt(args[0]);
moves(n, true);
}

}

Helen's credit card has an apr of 15.32% and a grace period of 17 days and helen pays her balance in the full every month. if her last billing cycle ended on september 26, 2009, and she made her payment on october 11, 2009, did she owe any interest on her last statement's balance?

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."

Can someone work out the answer as it comes up in one of my computer science exams and i don't understand the cryptovariables
