    1. You are given a number n.

    2. You have to create a pattern as shown in the output format.

    Input format:

    A number n

    Output format:


    1 <= n <= 5

    Solution Approach:

    We have to print a triangle of Fibonacci sequence numbers in the given problem. Now, we have already discussed how to print the Fibonacci series and triangle of stars on the way to this problem.

    Using that knowledge, we will move forward to combine them and implement it in our program.

    import java.util.*;
                                    public class Main{
                                        public static void main(String[] args)
                                            Scanner scn = new Scanner(;
                                            int n = scn.nextInt();
                                            int a = 0,b = 1; // First two Fibonacci numbers
                                            for(int i =1;i<=n;i++)
                                                for(int j = 1;j<=i;j++)
                                                    System.out.print(a + "	");
                                                    int c = a + b;  //Since next fibonacci number is sum of                    
                                                    a = b;         //previous two fibonacci numbers
                                                    b = c;

    java false
