(JAVA)Determine the output of the following code. You must show the values of the variables as you iterate through the loop for full credit.

public static double timesTwo(double num) {    double result = num * 2; }   1)what is the problem? 2) How will fix it?

[Python Language]   A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.

(5) The following code was intended for obtaining the number of times you have to divide 1 by 2 to get a value less than one ten-thousands (0.0001). Please point out errors and correct/complete the JAVA code.        //Declare variables      int number = 1;      double quotient = number/2;      while(quotient>=0.0001);      {               quotient = quotient/2;      }
