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

number of pennies after 10 days: 1024

note: these activities may test code with different test values. this activity will perform three tests, with startingpennies = 1 and userdays = 10, then with startingpennies = 1 and userdays = 40, then with startingpennies = 1 and userdays = 1. see how to use zybooks.

also note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message.

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;
}
