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 that Alan starts to play the game.
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 time that Alan closes the game.

One line contains three integers $h_{tot}\ m_{tot}\ s_{tot}$ － the amount of time that Alan plays the video game.
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 $0$.
