D - 1sting(相当于斐波那契数列，用大数写)

Description

You will be given a string which only contains ‘1’; You can merge two adjacent ‘1’ to be ‘2’, or leave the ‘1’ there. Surly, you may get many different results. For example, given 1111 , you can get 1111, 121, 112,211,22. Now, your work is to find the total number of result you can get. 

 

Input

The first line is a number n refers to the number of test cases. Then n lines follows, each line has a string made up of ‘1’ . The maximum length of the sequence is 200. 

 

Output

The output contain n lines, each line output the number of result you can get . 

 

Sample Input

3 1 11 11111

 

Sample Output

1 2 8

简单题，用java中的大数写

注意类名Main

 

package test;
import java.util.Scanner;
import java.math.BigInteger;
public class Fib {
    static BigInteger[] num = new BigInteger[205];
    static String s;
    public static void main(String[] args){
        num[1] = new BigInteger("1");
        num[2] = new BigInteger("2");
        for(int i = 3; i <= 201; i++){
            num[i] = num[i-1].add(num[i-2]);
            //System.out.println(num[i]);
        }       

        Scanner in = new Scanner(System.in);
        System.out.println("输入n");
        int n = in.nextInt();
        int flag = 1;
        while((n--) != 0){
            System.out.println("输入字符串");
            if(flag == 1){
                in.nextLine();
                flag = 0;
            }
            s = in.nextLine();
            int len = s.length();
            System.out.println(num[len]);
        }
    }
