In this post, we will see how to Print Numbers from 1 to N without using loop.
Problem
Print Number from 1 to N without using any loop.
N=10
Output: 1 2 3 4 5 6 7 8 9 10
Output: 1 2 3 4 5 6 7 8 9 10
Using Recursion
We can use tail recursion to solve this problem.
- Base case
- When n
- call printNumbers recursively with n-1
- Print number while returning from recursion.
package org.arpit.java2blog;
public class PrintNumbersWithoutLoop {
public static void main(String[] args) {
PrintNumbersWithoutLoop pnwl=new PrintNumbersWithoutLoop();
pnwl.printNumbers(10);
}
public void printNumbers(int n)
{
if(nOutput
1 2 3 4 5 6 7 8 9 10
That’s all about how to print Numbers from 1 to N without using loop.
