The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

1. 在IBConsole中添加两个用户LOGIN和MATER，密码均为PASSWORD。 2. 用MISDBA用户登录MISDB数据库。 3. 在ISQL中，输入第9章提供的SQL语句；或者根据表9-1至表9-8在SQL Explorer中自行创建数据表。数据库创建后需要分配LOGIN和MATER用户的访问权限。 4. 根据表9-9和表9-10设置初始数据，另外需要在PERSON数据表中设置一个用于登录系统的用户（ID=’MAT’，PASSWD=’PASSWORD’，AUTHORITY=’7’，STATE=’F’），同时在PART表中添加ID为’0000000000’的零件，名称为“。 5. 除了修改数据库连接的属性，还需要修改数据模块中LOGIN方法的相关用户密码。

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.
