Which of the following is/are true regarding the characteristics of recursion? a.Every recursive call reduces the original problem, bringing it increasingly closer to a base case until it becomes that case. b.Recursive method requires less memory than an iterative method. c. It is possible to convert every recursive method to an iterative method. d.The method is implemented using an if-else or a switch statement that leads to different cases. e.One or more base cases are used to stop recursion.

Demonstrate your understanding of recursion by creating a recursive method of your own. Start with the recursive method outline below: int recurs (__________){ if (__________) return __________; // stopping base case else return __________; // recursive call} Fill in the blanks to create your own original recursive method. Post your method code. Then demonstrate a call to your recursive method that requires the method to call itself at least twice before the stopping case is encountered. For each pass (call) show: The values for the parameters of the call, going forward What values are passed back from the call, going back
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.
This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. Manually trace the recursive call, fn(2,3) and show the output (step by step). Can you identify the Base Case in recursive method fn(int x, int y)?
1. Let product(n,m) be a recursive method that computes the product of two positive integers, using only addition and subtraction. To make this method a recursive one, you are to make a) a base case when m = 1, b) a general case when m ≠ 1. For a general case, the return value should be n plus the result of a recursive call to the method product() with parameters n and m - 1. Write a short Java code for this method, along with a test program.
JAVA Question 2: For two integers m and n, their GCD (Greatest Common Divisor) can be computed by a recursive method. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Method body: If m is 0, the method returns n. If n is 0, the method returns m. If neither is 0, the method can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n (or m % n). The recursive method cannot have loops. Note: although there are other approaches to calculate Greatest Common Divisor, please follow the instructions in this question, otherwise you will not get the credit. main method: Prompt and read in two numbers to find the greatest common divisor. Call the gcd method with the two numbers as its argument. Print the result to the monitor. Example program run: Enter m: 12 Enter n: 28 GCD(12,28) = 4 And here is what I have so far, package CSCI1302;import java.util.*;public class RecursionDemo { public static void…
Question) Which of the following is NOT a good strategy for designing recursive methods? A recursive method should include at least one conditional statement. A recursive method should establish a base case. A recursive method should reduce the problem to a smaller problem or problems and call itself recursively to solve the smaller problem(s). When the base case is reached stop the program and display results.
You are given a string of characters. Complete the below recursive method in JAVA or inPython to print the lowercase characters in a reverse manner and also print the count. Scontains the string, i is the starting index and c is the count, which are both initialized to0. [Note for Python Implementation: You are not allowed to use any built-in functionsexcept len(), print(), ord() and chr()]. def printReverse (s, i, c) : #To Do OR public void printReverse (String s, int i, int c) { // To Do } Sample Input Sample Output s = Axy3*8Gw57&Xyu1 count is 4, uwyx

PLZ help with the folllowig IN JAVA TRUE OR FALSE When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. 2.Can you have a static method in a nonstatic inner class?
Given the sequence, S2 = 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, … Write a RECURSIVE method called “sequence2” that takes a single int parameter (n) and returns the int value of the nth element of the sequence S2. You will need to determine any base cases and a recursive case that describes the listed sequence. Use the following code to test your answers to questions 3 and 4the output should print the two sequences given (S & S2): public class TestSequences { public static void main(String[] args) { for(int i = 0; i < 10; i++) { System.out.print(sequence(i) + " "); // 2, 4, 6, 12, 22, 40, 74, 136, 250, 460 } System.out.println(); for(int i = 0; i < 10; i++) { System.out.print(sequence2(i) + " "); // 1, 2, 4, 5, 7, 8, 10, 11, 13, 14 } } // *** Your method for sequence here *** // *** Your method for sequences2 here *** } // end of TestSequences class
