Write code to complete doublePennies()'s base case. Sample output for below program:

Number of pennies after 10 days: 1024 

public class CalculatePennies { // Returns number of pennies if pennies are doubled numDays times public static long doublePennies(long numPennies, int numDays) { long totalPennies = 0;

/* Your solution goes here */

else { totalPennies = doublePennies((numPennies * 2), numDays - 1); } return totalPennies; }

// Program computes pennies if you have 1 penny today, // 2 pennies after one day, 4 after two days, and so on public static void main (String [] args) { long startingPennies = 0; int userDays = 0;

startingPennies = 1; userDays = 10; System.out.println("Number of pennies after " + userDays + " days: " + doublePennies(startingPennies, userDays)); return; } }
