Write code to complete doublePennies()'s base case. Sample output for below program with inputs 1 and 10: Number of pennies after 10 days: 1024 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 */

     if(numDays == 0){

         totalPennies = numPennies;

     }

     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;

  }

}

Explanation:

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
