Problem Statement: Staircase

Description:

You need to write a program that prints a staircase of size n using # symbols and spaces. The staircase is right-aligned, meaning the last line is not preceded by any spaces. Both the base and height of the staircase are equal to n.

Input Format:

• A single integer n, denoting the size of the staircase.

Constraints:

• 0<𝑛≤100

Output Format:

• Print a staircase of size n using # symbols and spaces.

Input:

Function Signature:

6

Output:

Function Signature:

     #
    ##
   ###
  ####
 #####
######

Explanation: The staircase is right-aligned, composed of # symbols and spaces, and has a height and width of n = 6.

Example Solution in C++:

Function Signature:

#include <iostream>
using namespace std;

void staircase(int n) {
    for(int row=1;row<=n;row++){
        for(int col=1;col<=n;col++){
            if((row+col)>n)
                cout<<"#";
            else
                cout<<" ";
        }
        cout<<endl;
    }
}

int main() {
    int n;
    cout << "Enter the size of the staircase: "<<endl;
    cin >> n;

    if (n > 0 && n <= 100) {
        staircase(n);
    } else {
        cout << "Invalid input. Please enter a number between 1 and 100." << endl;
    }

    return 0;
}

Explanation:

The function staircase takes an integer n as a parameter.

It uses nested loops to print the staircase:

• The outer loop runs from 1 to n, creating each level of the staircase.

• The first inner loop prints the required number of spaces.

• The second inner loop prints the # symbols.

In the main function, the user is prompted to enter the size of the staircase.

• The input is validated to ensure it is within the specified range.

This code will create a staircase of the given size, right-aligned, with # symbols and spaces.
