Description
Now that you’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. A combination consists of 3 of these numbers; for example: 15258. 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 2nd number is reached
turn the dial clockwise again until the 3rd 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. 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 0 0 0 0 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.
Sample Input
0 30 0 305 35 5 350 20 0 207 27 7 270 10 0 109 19 9 190 0 0 0
Sample Output
135013501620162018901890
注意：题目是刻度盘在转动而不是指针，还有问的是转盘转过的度数此题理清思路后便不难
