How to print "Hello" N times (where N is user input) without using loop or recursion or goto.

Input : N, that represent the number of times you want to print the statement. Output : Statement for N times

First, we create a class. After that, we need to initialize the constructor of the class by writing the statement you want to print inside a cout/print statement. The basic idea used here that "The no. of times you create the object of the class, the constructor of that class is called that many times."

CPP

// CPP program to print a sentence N times
// without loop and recursion.
// Author : Rohan Prasad
#include <iostream>
using namespace std;
class Print {

public:
  Print()
  {
    cout << "Hello" << endl;
  }
};

int main()
{
  int N = 5;
  Print a[N];
  return 0;
}

Python3

class Print:
    def __init__(self):
        print("Hello")

N = 5
a = [Print() for i in range(N)]

Output:

Hello
Hello
Hello
Hello
Hello

Time Complexity: O(N)

Auxiliary Space: O(N)

Extra space is required for array initialisation.

How will you print numbers from 1 to 100 without using a loop?

If we take a look at this problem carefully, we can see that the idea of "loop" is to track some counter value, e.g., "i = 0" till "i <= 100". So, if we aren't allowed to use loops, how can we track something in the C language?Well, one possibility is the use of 'recursion', provided we use the t
