Staircase

Staircase detail

This is a staircase of size :

   #
  ##
 ###
####

Its base and height are both equal to n. It is drawn using # symbols and spaces. The last line is not preceded by any spaces.

Write a program that prints a staircase of size n.

Example:

Input:  4

Output:

   #
  ##
 ###
####

Approach

Java

public class Staircase {
    public static void main(String[] args) {
        int n = 4;
        staircase(n);
    }

    static void staircase(int n) {
        int i, j;
        for (i = 1; i <= n; i++) {
            for (j = 1; j <= n; j++) {
                if (j >= n + 1 - i) {
                    System.out.print("#");
                } else {
                    System.out.print(" ");
                }
            }
            System.out.println();
        }
    }
}

C++

#include <bits/stdc++.h>
using namespace std;

int main()
{
    int n = 4;
    int i, j;
    for (i = 1; i <= n; i++)
    {
        for (j = 1; j <= n; j++)
        {
            if (j >= n + 1 - i)
            {
                cout << "#";
            }
            else
            {
                cout << " ";
            }
        }
        cout << "\n";
    }
    return 0;
