Description: ary[]{1,2,3,4} 求打印其的所有子集。这是关于【幂集】的问题。
【幂集】包括【全集】和【空集】。对于有N个元素的集(/ □ \)合，它的幂集个数有2的N次方个。
比如这个例子，数组有4个元素。那么用4个位表示每一个元素（假设从左到右表示1234吧），0表示该数不存在，1表示存在。
则：
0000表示空集｛｝。
0001表示｛4｝。
0010表示｛3｝；
0011表示｛3，4｝；
…………
1110表示｛1，2，3｝；
1111表示｛1，2，3，4｝。-ary [] {1,2,3,4} request to print all of its subsets. This is about power set】 【problems. Including the power set】 【Collection】 and 【】 【empty set. For N elements of the set (/ □ \) together, it is the power set of the number of N-th power of 2 months. Such as this example, the array has 4 elements. So with four bits of each element (assuming that 1234 bar from left to right), and 0 indicates that the number does not exist, one that exists. Then: 0000 represents the empty set {}. 0001 {4} said. 0010 that {3} 0011 for {3,4} ... ... ... ... 1110 that {1,2,3} 1111 that {1,2,3,4}.

输入：input.txt，仅包含整数n（1－26）。
输出：若输入合法，输出集合的所有子集；否则输出"WRONG"。子集输出格式为每行一个子集，空集用空行表示，非空集合每个元素间用一个空格间隔，最后一个元素之后不能有空格。-Write a recursive function, an n-element set of all subset of. May wish to make a collection of elements to lowercase letters, the original set is {' a' , ' b' , ..., ' a' + n- 1}. Input: input.txt contains only the integer n (1-26). Output: enter a valid subset of the output collection otherwise output " WRONG" . A subset of a subset of the output format for each line, empty set with an empty line, non-empty set with a space interval between each element of an element can not have spaces.

Description: Apriori算法用于发现数据中的频繁项集以及关联规则，属于关联分析，
关联分析的目标包含两条：发现频繁项集和发现关联规则。
该算法基于一个很重要的原理，apriori原理，如果某个相机是频繁的，那么他的所有子集也是频繁的，
也就说，如果一个项集是非频繁的，那么它的所有超集也是非频繁的。
Apriori算法是先生成C1->L1->C2->L2->C3.Apriori算法的缺点是很明显的，每生成一个频繁项集，都要扫描整个数据集。
在数据规模很大的时候，这个是致命的性能瓶颈。
-Apriori algorithm is used to find data itemsets and association rules, are associated with analysis,
Association analysis included two goals: find frequent itemsets and association rules discovery.
The algorithm is based on a very important principle, apriori theory, if a camera is frequent, then all subsets also his frequent,
Also said that if a non-frequent item sets, then it is also a superset of all the non-frequent.
Apriori algorithm is Mr. Cheng C1-> L1-> C2-> L2-> shortcomings C3.Apriori algorithm is obvious, each generating a frequent item sets, must scan the entire data set.
When a large-scale data, this is the fatal performance bottleneck.
