The primary goal of MySQL and Java Developer’s Guide is to provide a comprehensive approach to writing code from a Java application to a MySQL database using the industry standard: JDBC. As you will see later in this Introduction, the chapter titles indicate what area of database connectivity and manipulation they cover. The chapters are ordered to reflect the JDBC specification, but we aren’t here to simply describe the specification.

給定兩個(gè)集合A、B,集合內(nèi)的任一元素x滿足1 ≤ x ≤ 109,并且每個(gè)集合的元素個(gè)數(shù)不大于105。我們希望求出A、B之間的關(guān)系。 任 務(wù)?。航o定兩個(gè)集合的描述,判斷它們滿足下列關(guān)系的哪一種: A是B的一個(gè)真子集,輸出“A is a proper subset of B” B是A的一個(gè)真子集,輸出“B is a proper subset of A” A和B是同一個(gè)集合,輸出“A equals B” A和B的交集為空,輸出“A and B are disjoint” 上述情況都不是,輸出“I m confused!”

This routine calls the glpk library to solve a LP/MIP problem. A typical LP problem has following structure: [min|max] C x s.t. Ax ["="|"<="|">="] b {x <= UB} {x >= LB} The calling syntax is: [XMIN,FMIN,STATUS,EXTRA]=glpkmex(SENSE,C,A,B,CTYPE,LB,UB,... VARTYPE,PARAM,LPSOLVER,SAVE)

上下文無關(guān)文法(Context-Free Grammar, CFG)是一個(gè)4元組G=(V, T, S, P),其中,V和T是不相交的有限集,S∈V,P是一組有限的產(chǎn)生式規(guī)則集,形如A→α,其中A∈V,且α∈(V∪T)*。V的元素稱為非終結(jié)符,T的元素稱為終結(jié)符,S是一個(gè)特殊的非終結(jié)符,稱為文法開始符。 設(shè)G=(V, T, S, P)是一個(gè)CFG,則G產(chǎn)生的語言是所有可由G產(chǎn)生的字符串組成的集合,即L(G)={x∈T* | Sx}。一個(gè)語言L是上下文無關(guān)語言(Context-Free Language, CFL),當(dāng)且僅當(dāng)存在一個(gè)CFG G,使得L=L(G)。 *⇒ 例如,設(shè)文法G:S→AB A→aA|a B→bB|b 則L(G)={a^nb^m | n,m>=1} 其中非終結(jié)符都是大寫字母,開始符都是S,終結(jié)符都是小寫字母。

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.
