Print Right Pascal’s Triangle with Increasing Order Repeated Number Pattern

In the previous article, we have discussed Java Program to Print Right Pascal’s Triangle Number Pattern

In this article we are going to see how to print the right Pascal’s triangle with increasing order repeated number pattern.

Example-1

When row value=4

1
2 2
3 3 3
4 4 4 4
5 5 5
6 6
7
Example-2:

When row value=5

1
2 2
3 3 3
4 4 4 4
5 5 5 5 5
6 6 6 6
7 7 7
8 8

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

Approach:

  • Enter total row and store it in an integer variable rows.
  • Take one outer for loop to iterate the rows.
  • Take two inner for loops,  to print the characters of upper half and lower half triangle.
  • After each iteration print a new line.

Java Code to Print Right Pascal’s Triangle with Increasing Order Repeated Number Pattern

import java.util.Scanner;
class Main
{
public static void main(String[] args)
{
    //Create a new Scanner object
    Scanner scan = new Scanner(System.in);

    //Taking number of rows as input from user
    System.out.print("Rows : ");
    int rows = scan.nextInt();

    //Row and column are the iterators
    int numberOfRows, numberOfColumns, tempHolder=1;

    //Outer loop to iterate the rows (upper half)
    //Iterates from 1 to number of rows entered by the user
    for (numberOfRows = 1; numberOfRows<=rows; numberOfRows++)
    {
        //Inner loops to iterate the columns
        for (numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
        {
            //Prints number
            System.out.print(tempHolder+ " ");
        }
        tempHolder++;
        //Prints a newline
        System.out.println();
    }

    //Second outer loop to iterate the rows (lower half)
    //Iterates from number of rows entered by the user to number 1
    for (numberOfRows = rows; numberOfRows>=1; numberOfRows--)
    {
        //Inner loops to iterate the columns
        for (numberOfColumns = 1; numberOfColumns < numberOfRows; numberOfColumns++)
        {
            //Prints number
            System.out.print(tempHolder+ " ");
        }
        tempHolder++;
        //Prints a newline
        System.out.println();
    }
}
}

Output:

Rows : 5

1
2 2
3 3 3
4 4 4 4
5 5 5 5 5
6 6 6 6
7 7 7

C to Print Right Pascal’s Triangle with Increasing Order Repeated Number Pattern

#include <stdio.h>

int main()
{
    //Taking total number of rows as input from user
    printf("Rows : ");
    int rows;
    scanf("%d", &rows);

    //Row and column are the iterators
    int numberOfRows, numberOfColumns, tempHolder = 1;

    //Outer loop to iterate the rows (upper half)
    //Iterates from 1 to number of rows entered by the user
    for (numberOfRows = 1; numberOfRows <= rows; numberOfRows++)
    {
        //Inner loops to iterate the columns
        for (numberOfColumns = 1; numberOfColumns <= numberOfRows; numberOfColumns++)
        {
            //Prints number
            printf("%d ", tempHolder);
        }
        tempHolder++;
        //Prints a newline
        printf("\n");
    }

    //Second outer loop to iterate the rows (lower half)
    //Iterates from number of rows entered by the user to number 1
    for (numberOfRows = rows; numberOfRows >= 1; numberOfRows--)
    {
        //Inner loops to iterate the columns
        for (numberOfColumns = 1; numberOfColumns < numberOfRows; numberOfColumns++)
        {
            //Prints number
            printf("%d ", tempHolder);
        }
        tempHolder++;
        //Prints a newline
        printf("\n");
    }
