Chapter 16, Problem 1MC
Program Description Answer

When a method is called from the main method then, it calls itself four times and the depth of the recursion will be four.

Hence, the correct option is “B”.

Expert Solution & Answer
Check Mark

Explanation of Solution

Four:

The depth of the recursion depends on the number of times the method calls itself.

Explanation for incorrect options:

One:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, option “A” is wrong.

Five:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, the option “C” is wrong.

Nine:

The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.

Hence, the option “D” is wrong.

Python Programming ONLY PLEASE NO JAVA  Use recursion to determine the number of digits in an integer n.  Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10.  Write the method and then write a test program to test the method Your test program must:   Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.
1. Create a Java program with three static methods in addition to the main method 1) Factorial Method (recursion method to calculate the factorial of an integer number) 2) Fibonacci Medhod (recursion method to calculate the fibonacci of an integer number) 3) Display Method (take a String and integer mumber as parameters then display the factorial sequence if the String = "Factorial" and display fibonacci sequence if String = "Fibonacci". Otherwise, display "Invalid choice input") Guideline for developing the application. Input Output Start program by invoking the Display method then test is run: Fibonacci (6) -> 0 11 2 3 5 8 13 Factorial (5) -> 5 * 4 * 3 * 2* 1 - 120 with the following values: - 13 Display("Fibonacci", 6); Invalid choice input: test BUILD SUCCESSFUL (total time: 1 second) Display("Factorial", 5); Display("test", 5):
