A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15.
Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand back to 0.-clock to solve the problem, acm contest A weird clock marked from 0 to 59 has only a minute hand.

Description: 怪异钟
一个钟只有分针（仅能表示0~59分），它自己不会走，只有投入一种硬币，它才会走。硬币上标有一个数字d，则该钟向前走当前时间s（分钟）的d倍，例如当时钟分针为45分钟时(s=45)，投入d=2的硬币，该钟将向前走45*2=90分钟，指向15分。现在输入时钟的当前分钟，和硬币上的数字d，问最少投入多少个这样的硬币后指针指向0点，如果永远不可能指向0点，则输出impossible。
-Weird clock a clock the minute hand only (can only be expressed from 0 to 59 points), which he will not go, and only put a coin, it will go. Coins a number d, the clock to move forward the current time s (min) d times, for example, when the clock minute hand is 45 minutes (s = 45), investment in d = 2 coins, the clock will move forward 45* 2 = 90 minutes walk, point to 15 points. The number d in the current minute of the input clock and coins, ask for at least put into the number of coins after the pointer to point to 0:00, if you never point to 0:00, then the output impossible.
