-----------------------------------------

 

迭代相加即可

 

AC代码：

import java.math.BigInteger;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        
        Scanner sc=new Scanner(System.in);
        
        while(sc.hasNextBigInteger()){
            BigInteger a=sc.nextBigInteger();
            BigInteger b=sc.nextBigInteger();
            BigInteger c=sc.nextBigInteger();
            for(int i=3;i<=99;i++){
                BigInteger t=c.add(b).add(a);
                a=b;
                b=c;
                c=t;
            }
            
            System.out.println(c.toString());
        }
    }
    
}
