Problem 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

        s[2] = new BigInteger("2");
        for(int i=3;i<=200;i++)

        int n = cin.nextInt();       
        for(int i=0;i<n;i++)
        {
        	String S = cin.next();
        	int l = S.length();
        	
        	System.out.println(s[l]);
        }
    }
