Problem F
Combination Lock
Now that youâ€™re back to school for another term, you need to remember how to work the combination lock on your locker. A common design is that of the Master Brand, shown at right. The lock has a dial with $40$ calibration marks numbered $0$ to $39$ with $0$ at the top and then increasing in clockwise order. A combination consists of $3$ of these numbers; for example: $15$$25$$8$. To open the lock, the following steps are taken:

turn the dial clockwise $2$ full turns

stop at the first number of the combination

turn the dial counterclockwise $1$ full turn

continue turning counterclockwise until the $2$nd number is reached

turn the dial clockwise again until the $3$rd number is reached

pull the shank and the lock will open.
Given the initial position of the dial and the combination for the lock, how many degrees is the dial rotated in total (clockwise plus counterclockwise) in opening the lock?
Input
Input consists of several test cases, at most $2\, 000$. For each case there is a line of input containing $4$ numbers between $0$ and $39$. The first number is the position of the dial. The next three numbers are the combination. Consecutive numbers in the combination will be distinct. A line containing four zeros follows the last case.
Output
For each case, print a line with a single integer: the number of degrees that the dial must be turned to open the lock.
