Java Program to print Pascal Triangle

We are going to create a source code that prints the Pascal Triangle.

A Pascal Triangle is not just a big triangular pattern of numbers. There are two major areas where Pascal’s Triangle is used: Algebra and Probability/Combinatorics.

Source Code:

/* Program to print Inverted Pascal Triangle*/
import java.util.*;
class NumPascal
{
public static void main()
{
Scanner inp=new Scanner(System.in);
System.out.print("\n Enter Size Limit: ");
int n=inp.nextInt();
int i,j,x=1;
System.out.println("Pascal Triangle: \n");

for(i=1;i<=n;i++) { for(j=n;j>i;j--) { System.out.print(" "); } x=1; for(j=1;j<=i;j++) { System.out.print(j+" "); x=x*(i-j)/(j+1); } System.out.println(); }

} }

Output:

Enter Size Limit: 6
Pascal Triangle: 
 1 
1 2 

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