Question

In C# Problem 1: Order matters! For this question, you’re going to write two recursive functions, both of which take in only a single string as a parameter; you will not receive credit if you pass in an integer as well. Note: you will need to understand substrings to get the correct solution. The first function should simply print out the string, but do so letter by letter – and recursively. The second function should print out the string in reverse; the code is almost identical, but the concept is different. Hint, note the title of the problem. Example Output: Hello world! !dlrow olleH

Problem 2: Summing up sums. For this question, you’ll understand the importance of using the results of smaller sets of work. You’re going to create a recursive function that takes in an array of random integers and returns a “sum of sums”. This is best explained through an example. If you have 5 elements in an array, the function should return the sum of elements 0-4, 1-4, 2-4, 3-4, and 4. So, if we had an array of: 5, 18, 4, 7, 11 The sum of sums would be (45+40+22+18+11) = 136. Hint: is the sum of sums not just the sum of the current array + the sum of sums of an array?

Answer 1

using System;

class MainClass {

  public static void func1 (string x) {
          if(x.Length != 0) {
                Console.Write(x[0]);
                func1(x.Substring(1));
          }
  }
  public static void func2 (string x) {
          if(x.Length != 0) {
                func2(x.Substring(1));
                Console.Write(x[0]);
          }
  }

  public static void Main (string[] args) {
    func1("hello world!");
    Console.Write(" ");
    func2("hello world!");
  }
}
