解決時鐘問題，acm競賽題
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.
Micro In-System Programmer Brief Installation Notes
Enter the src directory.
If uisp does not compile successfully, add switch -DNO_DIRECT_IO in the
Makefile to remove support for direct I/O port access (that may be
necessary on non-PC architectures). Parallel port access should still
work if you have the Linux ppdev driver (patch for 2.2.17 is in the
kernel directory, ppdev is standard in 2.4 kernels). Please lobby
Alan Cox to include this tiny little driver in 2.2.x too :).
To make it type:
make
and to install it:
make install
If you have any further doubts, please consult UISP s homepage:
