Question Question 18
Write a program to read the number n using the Scanner class and print the Tribonacci series: 0, 0, 1, 1, 2, 4, 7, 13, 24, 44, 81 ...and so on.
Hint: The Tribonacci series is a generalisation of the Fibonacci sequence where each term is the sum of the three preceding terms.
import java.util.Scanner;
public class KboatTribonacci
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter no. of terms : ");
int n = in.nextInt();
if(n < 3)
System.out.print("Enter a number greater than 2");
else {
int a = 0, b = 0, c = 1;
System.out.print(a + " " + b + " " + c);
for (int i = 4; i <= n; i++) {
int term = a + b + c;
System.out.print(" " + term);
a = b;
b = c;
c = term;
}
}
}
}Output
