D

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

        for(int i = 3; i <= 201; i++){               
            num[i] = num[i-1].add(num[i-2]);       
            //System.out.println(num[i]);
