表

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 Class: Alphabet Method: choices Parameters: string Returns: int Method signature: int choices Constraints decree contains between 1 and 25 characters inclusive.

我注：如上面的BAA有3个字符，那么新表就有4个，也就是'd'后面的全被忽略创建一个名为Alphabet的类，此类含有一个名为choices方法，choices方法以&规定&作为参数输入，然后返回所有符合这个规定的新字母表的可能数，如果大于1，000，000，000可能，就返回-1 定义：类名：Alphabet 方法：choices 参数类型：string 返回值类型：int 方法签名：int choices (确保choices为公有方法)参数条件：规定中的'B'和'A'总和必须大于等于1，小于等于25 举个例输入：&BAA&返回：3 解释：因为根据规定'a'在'b'的前面，'b'在'c'的后面，'c'在'd'的后面，所有符合这个规定的新字母表有3个：adcb、dacb和

The economic list that the article carries pair of chief Nai, investment that lists the husband that hold a section high yields system of account of the watch of integrated finance balance of watch, MPS, countryman the introduction that big matrix expresses, analysis, show circumstance of their respective suitable scope, research and its effect.

The test comes primarily in two forms:the Stanford Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children's version).

测试主要采用两种形式：一种是斯坦福-比奈智力量表，一种是温切斯勒智力量表（两个量表均有成人和儿童两个版本）。

During the construction of medical experiment teaching evaluation system, we must definitude the characteristics of guide direction, science, feasibility, effect and comparability. Firstly, the author constructed the pretest questionnaire by literature study, brain storm and specialist counseling. Secondly, the author uses t-test and exploring factors analysis to construct index system. Lastly, the author evaluated formal questionnaire's reliability and validity by approving factors analysis and correlation test.

在医学实验教学质量评价指标体系的构建中，必须明确导向性、全面性、科学性、可操作性、有效性和可比性原则，首先采用文献研究法、头脑风暴法以及专家咨询等方法构建预试量表，其次对预试量表运用t检验、探索性因子分析的方法来构建指标体系，最后运用验证性因子分析和相关性研究对正式量表进行效度和信度检验。

Dial, the hour mark to 8 diamonds and elegant Arabic numerals were highlighted out of hours can also be form ring showing a day / night comparison of state, all-black city ring can bring out the elegant mother-of-pearl Pui dial, black crocodile also allows leather strap and crown on the charming agate better, in order to allow this expression to the perfect realm, which table table inlaid circle has 54 diamonds (1.95 carats), and stainless steel watchcase embraced each other.

拨号，一小时至8钻石标志，优雅的阿拉伯数字强调了几个小时内也可以形成环呈现出昼/夜的状态相比，全黑的城市环能带出的优雅的珍珠母贝表盘，黑鳄鱼还允许在迷人的玛瑙更好的皮表带及冠，以便让这种完美的境界，这表的表圈镶嵌的表达有54个钻石（1.95克拉），和不锈钢表壳互相拥抱。

With regards to the learning motive of music, after excluding the pretest influence, it is the finding of the study that the students belonging to the experimentation group score higher in the areas of "Total score","Internal goal orientation","Work value","Controlled belief","Expectation to succeed" and "Test on anxiety" than the control group, amongst which "Work value" reaches significant difference on the measurement chart; of all the students scoring high on "Selective attention" during pretest, the experimentation group scores higher than the control group on posttest scores; regarding the students with lower pretest scores, the control group performs better than the experimentation group; of the students with higher pretest scores on "Discrete attention", the posttest scores of experimentation group are higher than those of the control group; regarding students with lower pretest scores, the control group performs better than the experimentation group; on "Sustained attention", the posttest scores of the experimentation group are higher than those of the control group; on the "Total score" of multidimensional attention measurement, the posttest scores of the experimentation group are higher than those of the control group.

研究结果发现，在音乐学习动机方面，经排除前测影响后，实验组学生在「总分」及「内在目标导向」、「工作价值」、「控制信念」、「期望成功」、「测试焦虑」等分量表上皆高於对照组，其中在「工作价值」分量表上达到显著性差异；在「选择性注意力」前测分数较高学生中，后测成绩为实验组显著优於对照组，对前测分数较低学生而言，则是对照组显著优於实验组；在「分离性注意力」前测分数较高学生中，后测成绩为实验组显著优於对照组，对前测分数较低学生而言，则是对照组显著优於实验组；在「持续性注意力」方面，后测成绩为实验组显著优於对照组；在多向度注意力量表「总分」方面，后测成绩为实验组显著优於对照组。

Department of this type of table movement modeled on the Roman table, 17 drill, third pin, waterproof shockproof Antimagnetic, core thickness of 4.62mm, a diameter of 42.6mm, watchcase watchcase for steel.

该型表系仿照罗马表机芯，17钻，大三针，防水防震防磁，机芯厚度为4.62mm，直径为42.6mm，表壳为全钢表壳。

Over the years, the company has organized development and production of intelligent IC card water, electricity, gas meter products, wireless meter reading system and intelligent IC card industrial gas meter three series of more than 20 varieties, and intelligent electronic control products.

多年以来，公司先后组织开发、生产了IC卡智能水、电、气表系列产品、无线抄表系统和IC卡智能工业燃气表三大系列20多个品种和电子智能控制产品。

Entries in the table have explicit addends, such as Elf32_Rela for the 32-bit file class.

Rela类型重定位表中的表项会有一个明确的加数，比如32-bit类型的文件具有的 Elf32_Rela数据结构的重定位表项。

The split between the two groups can hardly be papered over.
