Chapter 11, Problem 5E
Complete a recursive definition of the following method:
/**
Precondition: n >= 0.
Returns 10 to the power n.
*/
public static int computeTenToThe (int n)
Use the following facts about xn:
xn = (xn/2)2 when n is even and positive
xn = x(x(n–1)/2)2 when n is odd and positive
x0 = 1

Consider the following recursive method:
Public static int Fib(int a1, int a2, int n){ if(n == 1) return a1; else if (n == 2) return a2;else return Fib(a1, a2, n-1) + Fib(a1, a2, n-2);}
Please draw the recursion trace for Fib(2,3,5)

Write a recursive method largestDigitthat accepts an integer parameter and returns the largest digit value that appears in that integer. Your method should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. The following table shows several example calls:
Call
Value Returned
largestDigit(14263203)
6
largestDigit(845)
8
largestDigit(52649)
9
largestDigit(3)
3
largestDigit(0)
0
largestDigit(-573026)
7
largestDigit(-2)
2
Obey the following restrictions in your solution:
You may not use a String, Scanner, array, or any data structure (list, stack, map, etc.).
Your method must be recursive and not use any loops (for, while, etc.).
Your solution should run in no worse than O(N) time, where N is the number of digits in the number.
Write a recursive method that takes two integers n and m as parameters, where m is one digit number. The method should output odd digits in n that are greater then m. For example:
If n =374, m=5, the method should output 7
If n =5239, m=2, the method should output 9 3 5
The method prototype:
public static void printDigits(int n, int m)
