数据挖掘决策树Java源代码
资源描述决策树是建立在信息论基础之上,对数据进行分类挖掘的一种方法。其思想是,通过一批已知的训练数据建立一棵决策树,然后利用建好的决策树,对数据进行预测。决策树的建立过程可以看成是数据规则的生成过程。由于基于决策树的分类方法结构简单,本身就是人们能够理解的规则。其次,决策树方法计算复杂度不大,分类效率高,能够处理大数据量的训练集;最后,决策树方法的分类精度较高,对噪声数据有较好的健壮性,符合一般系统的要求。

说明: The famous Collatz sequence is generated by a method decribed as follows. Given a positive integer N, if it is odd, then replace it with 3*N+1. For even number N, use N/2 instead. You can get a sequence of number by this method. It is conjectured that the algorithm above will terminate at 1 for any integral input value. Despite the simplicity of the algorithm, it is unknown whether this conjecture is true. It has been verified, however, for all integers n such that 0 < n < 1,000,000 (and, in fact, for many more numbers than this.)
(Input
The first line contains a single integer T tells that there are T cases in the problem. Then for each case, there is an integers N.
Output
For each number N, output the sequence generated in a line, using coma as its separator.
