An integer y1 (0 ≤ y1 ≤ 10000), representing some quantity or size.
An integer m1 (1 ≤ m1 ≤ 12), representing some quantity or size.
An integer d1 (1 ≤ d1 ≤ 31), representing some quantity or size.
An integer y2 (0 ≤ y2 ≤ 10000), representing some quantity or size.
An integer m2 (1 ≤ m2 ≤ 12), representing some quantity or size.
An integer d2 (1 ≤ d2 ≤ 31), representing some quantity or size.

Multiple datasets will be given. If any of y1, m1, d1, y2, m2, or d2 is a negative number, the input will end. The number of datasets will not exceed 50.

### Example Input:

```
2006 9 2 2006 9 3
2006 9 2 2006 11 11
2004 1 1 2005 1 1
2000 1 1 2006 1 1
2000 1 1 2101 1 1
-1 -1 -1 -1 -1 -1
```

### Function Signature:
Write a function f(inputs) that takes in the input.
```python
def f(inputs: List[Tuple[int, int, int, int, int, int]]):
    '''
    inputs: a list of tuples, where each tuple contains six integers
    '''
```
