Given the start time and end time of a contest. Please calculate the amount of time for the contest.

The first line contains three integers $h_{st},\ m_{st},\ s_{st}\ (0\leq h_{st}<24,\ 0\leq m_{st},\ s_{st}<60)$, representing the start time of a contest.

The second line contains three integers $h_{ed},\ m_{ed},\ s_{ed}\ (0\leq h_{ed}<24,\ 0\leq m_{ed},\ s_{ed}<60)$, representing the end time of the contest.

It is guaranteed that the start time must be earlier than the end time.

One line contains three integers $h_{tot}\ m_{tot}\ s_{tot}$ － the amount of time for the contest.

The three integers must be in the ranges: $0 \leq h_{tot} < 24,\ 0 \leq m_{tot}, s_{tot} < 60$.

If any of the above integers has less than $2$ digits, fill in the prefix $0$. Please see the hint provided below.

06 23 54

08 51 39

08 51 39

02 27 45

Consider that $n=3$.

You can use

`cout << setw(2) << setfill('0') << n;`

to fill in the prefix $0$ if $n$ has less than $2$ digits.

That is, it prints out $03$.

Remember to add `#include <iomanip>`

before you use `setw()`

and `setfill()`
