Welcome to my first code golf challenge!
The Challenge: Tribonacci Numbers
For this challenge, I am asking you to write a program in any language of your choosing to accomplish a task. This week's task is to classify a number as a tribonacci number or not a tribonacci number.
A tribonacci number is like a fibonacci number, but each term is the sum of the three previous terms.
a0=0
a1=0
a2=1
a3=1
a4=2
a5=4
...
an=a(n-3)+a(n-2)+a(n-1)
In short, your program needs to read a number from the input and then output whether the number is a tribonacci number or not.
