Given the value of length, print the crown pattern using ‘*’ and ‘#’.
Note : In order to print a perfect crown, take the value of length as an odd number greater than 15.
Examples :
Input: length = 19 Output: * * * # # # ## ### ## ### ##### ### #### ####### #### ################### ################### ################### ******************* Input: length = 25 Output: * * * # # # ## ### ## ### ##### ### #### ####### #### ##### ######### ##### ###### ########### ###### ######################### ######################### ######################### ######################### *************************
Below is the implementation to print crown pattern :
C++
// C++ implementation to print // Crown pattern #include <bits/stdc++.h> using namespace std; // function to print crown pattern void crown(int length, int height) { for (int i = 0; i < height; i++) { for (int j = 0; j < length; j++) { // for first row, print '*' // i.e, for top part of crown if (i == 0) { // print '*' at first, middle and last column if (j == 0 || j == height || j == length - 1) { cout << "*"; } else { cout << " "; } } // print '*' at base of // crown i.e, for last row else if (i == height - 1) { cout << "*"; } // fill '#' to make a perfect crown else if ((j < i || j > height - i) && (j < height + i || j >= length - i)) cout << "#"; else cout << " "; } cout << "\n"; } } // Driver code int main() { // length of crown int length = 25; // height of crown int height = (length - 1) / 2; // function calling crown(length, height); return 0; } |
Java
// Java implementation to print // Crown pattern import java.io.*; class GFG { // function to print crown pattern static void crown(int length, int height) { for (int i = 0; i < height; i++) { for (int j = 0; j < length; j++) { // for first row, print '*' // i.e, for top part of crown if (i == 0) { // print '*' at first, middle and last column if (j == 0 || j == height || j == length - 1) { System.out.print("*"); } else { System.out.print(" "); } } // print '*' at base of // crown i.e, for last row else if (i == height - 1) { System.out.print("*"); } // fill '#' to make a perfect crown else if ((j < i || j > height - i) && (j < height + i || j >= length - i)) System.out.print("#"); else System.out.print(" "); } System.out.println(); } } // Driver code public static void main (String[] args) { // length of crown int length = 25; // height of crown int height = (length - 1) / 2; // function calling crown(length, height); } } // This code is contributed by vt_m. |
