Print K shape Number Pattern

In the previous article, we have discussed Java Program to Print Exponentially Increasing Number Pattern

In this article we will see how to print K shape number pattern.

Example-1

When size value=5

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
Example-2:

When size value=4

1 2 3 4
1 2 3
1 2
1
1
1 2
1 2 3
1 2 3 4

 Now, let’s see the actual program to print it.

If you are new to Java and want to learn the java coding skills too fast. Try practicing the core java programs with the help of the Java basic programs list available.

Approach:

  • Enter total size and number store them in integer variables size.
  • Take one for loop to the upper part of the k i.e. inverted right angle  tringle.
  • Take another outer for loop to the upper part of the k i.e.  right angle  tringle.

Java Code to Print K shape Increasing Number Pattern

import java.util.Scanner;
class Main
{
    public static void main(String[] args)
    {
        // taking size of no. of iteration 
        //Row and column are the iterators
        int size , numberOfRows , numberOfColumns ;
        // Create a new Scanner object
        Scanner scanner = new Scanner(System.in);
        // Get the number of rows from the user
        System.out.print("Enter the  size : ");
        size = scanner.nextInt();
        // this loop will print the upper part of the k i.e. mirrored right angle  tringle 
        for (  numberOfRows = size; numberOfRows >= 1; numberOfRows--)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                System.out.print(numberOfColumns + " ");
            System.out.println();
        }
        // this loop will print the lower part of the k i.e. right angle  tringle 
        for (  numberOfRows = 1; numberOfRows <= size; numberOfRows++)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                System.out.print(numberOfColumns + " ");
            System.out.println();
        }
    }
}

Output :

Enter the size : 5

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5

C Code to Print K shape Increasing Number Pattern

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{
       int size , numberOfRows , numberOfColumns ;
       double dist;
       printf("Enter the  size : ");
       scanf ("%d",&size);
      for (  numberOfRows = size; numberOfRows >= 1; numberOfRows--)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                 printf("%d ", numberOfColumns);
             printf("\n");
        }
        for (  numberOfRows = 1; numberOfRows <= size; numberOfRows++)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                 printf( "%d ", numberOfColumns );
            printf("\n");
        }
    return 0;
}

Output :

Enter the size : 5

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
1
1 2
1 2 3

C++ Code to Print K shape Increasing Number Pattern

#include <bits/stdc++.h>
using namespace std;
int main()
{
    
       int size , numberOfRows , numberOfColumns ;
       double dist;
       cout << "Enter the  size : " ;
       cin >> size;
      for (  numberOfRows = size; numberOfRows >= 1; numberOfRows--)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                cout << numberOfColumns  ;
            cout << "\n" ;
        }
  
        for (  numberOfRows = 1; numberOfRows <= size; numberOfRows++)
        {
            for (  numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
                cout << numberOfColumns ;
           cout << "\n";
        }
    return 0;
}

Output :

Enter the size : 5

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1

1 2
1 2 3
