Suppose we want to compute the amount of money in a bank account with compound interest. If the amount of money in the account is m, the amount in the account at the end of the month will be 1.005 m. Write a recursive method that will compute the amount of money in an account after t months with a starting amount of m.

- Write a recursive method using java to return the sum of all numbers less or equal n divisible by 2 and 3arrow_forwardWrite a recursive Java method that calculates the sum of n positive integer numbers. The math function is: f(n) = 1 + 2 + 3 + … + n. Jack, Peter and John were exploring a tunnel which allows only one person to pass through. Jack entered the tunnel first, followed by Peter. John entered the tunnel the last. The tunnel has a dead end. So the team has to turn back and retrieve from the tunnel one by one. Write a Java program based on a suitable data structure to simulate this process.arrow_forwardGiven the following recursive method: public static int think(int x) { if(x<10) if(x%2!=0) return x; else return 0; else if(x%2!=0) return x%10 + think(x/10); else return think(x/10); } Trace (in details) the calling of the above method with any input from your choice such that the returned value will be 19arrow_forward
- Choose the correct one for the following recursive method when n is 3 int recursiveSum(int n) {     if (n==0)            return 0;     return n+recursiveSum(n-1); }   a. First and Last recursive call share the same copy of parameter n in memory.  b. Every recursive call shares the same copy of parameter n in memory.  c. There will be a separate copy of parameter n in memory for each recursive call.   d. none of these  e. Only First and Last recursive call have separate copies of parameter n in memory.arrow_forwardIt is suspected that out of a set of 64 50p coins one of the coins is fake (i.e., lighter in weight than a genuine coin). With one weighing scale. (i)Give a detailed explanation on how you would go about determining the fake coin. (ii)What is the minimum number of times you need to use the scales to weigh the coins before identifying the fake coin?   (iii)Write a recursive method that returns the value of N! (N factorial). Explain why you would not normally use recursion to solve this problem.arrow_forwardWrite a recursive method that gives the following pattern(Write in Java language) run : 1 2 4 7 11 16 22 29 37 46arrow_forward
- write a recursive method that performs exponentiation raising a base to a power (the only math operations you are allowed to use are addition and subtraction)  JAVA PLEASEarrow_forwardUsing Java, write a function that calculates the factorial of a number N using recursive and non-recursive methods. Call both methods with multiple numbers and show that the results are the same.arrow_forwardWrite a recursive method called digitCount() that takes two integers, n and m as a parameter and returns the number of digits in n that are equal to m. Assume that n≥0 and 0≤m≤9 Ex: If the input is: 34443215 4 3  import java.util.Scanner; public class LabProgram {    /* TODO: Write recursive digitCount() method here. */    public static void main(String[] args) {   Scanner scnr = new Scanner(System.in);   int digits;       int n= scnr.nextInt();   int m= scnr.nextInt();   digits = digitCount(n, m);   System.out.println(digits);  }}arrow_forward
- Java Program: Recursive Method There are n people in a room where n is an integer greater then or equal to 2. Each person shakes hands once with every other person. What is the total number of handshakes in the room? Write a recursive method to solve this problem with the following header:public static int handshake(int n)where handshake(n) returns the total number of handshakes for n people in the room. To get you started if there are only one or two people in the room, then:handshake(1)=0handshake(2)=1arrow_forwardWrite a recursive method called reverseString() that takes in a string as a parameter and returns the string in reversed order. The main method is provided to read a string from the user and call the reverseString() method. Use Java. Ex: If the input of the program is: Hello the reverseString() method returns and the program outputs: Reverse of "Hello" is "olleH". Ex: If the input of the program is: Hello, world! the reverseString() method returns and the program outputs: Reverse of "Hello, world!" is "!dlrow ,olleH". Hint: Move the first character to the end of the returning string and pass the remaining sub-string to the next reverseString() method call.  import java.util.Scanner; public class LabProgram { /* TODO: Write recursive reverseString() method here. */public static void main(String[] args) {Scanner scnr = new Scanner(System.in);String input, result;input = scnr.nextLine();result = reverseString(input); System.out.printf("Reverse of \"%s\" is \"%s\".", input, result);}}arrow_forwardJava, Rewrite the following iterative method as a recursive method that computes the same thing. Note:  your recursive method will require an extra parameter.public int iterative1(int x){int count = 0, factor = 2;while (factor < x){if (x % factor == 0) count++;factor++;}return count;}arrow_forward
