ANARC05H - Chop Ahoy! Revisited!


Given a non-empty string composed of digits only, we may group these digits into sub-groups (but maintaining their original order) if, for every sub-group but the last one, the sum of the digits in a sub-group is less than or equal to the sum of the digits in the sub-group immediately on its right. Needless to say, each digit will be in exactly one sub-group.

For example, the string 635 can only be grouped in one sub-group [635] or in two sub-groups as follows: [6-35] (since 6 < 8.) Another example is the string 1117 which can be grouped in one sub-group [1117] or as in the following: [1-117], [1-1-17], [1-11-7], [1-1-1-7], [11-17] and [111-7] but not any more, hence the total number of possibilities is 7.

Write a program that computes the total number of possibilities of such groupings for a given string of digits.

Input

Your program will be tested on a number of test cases. Each test case is specified on a separate line. Each line contains a single string no longer than 25, and is made of decimal digits only.

The end of the test cases is identified by a line made of the word "bye" (without the quotes.) Such line is not part of the test cases.

Output

For each test case, write the result using the following format:

k. n

where k is the test case number (starting at 1,) and n is the result of this test case.

Example

Input:
635
1117
9876
bye

Output:
1. 2
2. 7
3. 2

yipeeeeeeee!! 15th problem now ;) cool

@ ;) : Max string length is only 25. So its not a matter of time. Even recursion will do without deeping out!

Naive Brute Force method is getting AC in 0.00 sec!!

easy one:)

yaah .. just changing gets() to scanf("%s") worked !!

In test cases lines are ending with "\r\n" (Windows style) instead of '\n'.
Don't use gets() to read input. Use scanf().

Nice problem. Some submissions in "TEXT" have been accepted. I guess it has to be disabled.

Dodgy white space on the input here too.

Something is wrong with the tests. I think there is no "bye". Break your code when the first character is not a digit.

Re: they have "bye", this error because of the wrong test index.
