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.

％ [BestPop,Trace]=fmaxga(FUN,LB,UB,eranum,popsize,pcross,pmutation)
％ Finds a maximum of a function of several variables.
％ fmaxga solves problems of the form:
％ max F(X) subject to: LB <= X <= UB
％ BestPop--------最優的群體即為最優的染色體群
％ Trace----------最佳染色體所對應的目標函數值
％ FUN------------目標函數
％ LB-------------自變量下限
％ UB-------------自變量上限
％ eranum---------種群的代數,取100--1000(默認1000)
％ popsize--------每一代種群的規模；此可取50--100(默認50)
％ pcross---------交叉的概率,此概率一般取0.5--0.85之間較好(默認0.8)
％ pmutation------變異的概率,該概率一般取0.05-0.2左右較好(默認0.1)
％ options--------1×2矩陣,options(1)=0二進制編碼(默認0),option(1)~=0十進制編碼,option(2)設定求解精度(默認1e-4)
LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client.
The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents.
When created, this DLL does not export any symbols. As a result, it
will not produce a .lib file when it is built. If you wish this project
to be a project dependency of some other project, you will either need to
add code to export some symbols from the DLL so that an export library
will be produced, or you can check the "doesn t produce lib" checkbox in
the Linker settings page for this project.
