in range (1,len (s)): if S[J-1]==S[J]: return False return TrueAnalysis -the sequence is ordered using the Python built-in function sorted () in the code, and the sorting algorithm ensures that the worst run time is O (Nlogn).When the sort is complete, the loop sequence runs at O (n). So the worst run time for this algorithm is O (NLOGN)Data

predictable, the algorithm generates a separate decision tree for each predictable column.The principle of the algorithm:The Microsoft decision tree algorithm generates a data mining model by creating a series of splits in the tree. These splits are represented as "nodes". Whenever an input column is found to be closely related to a predictable column, the

. Therefore, neither of these algorithms can be considered a good algorithm because, from a practical point of view, they cannot process the input data within a reasonable time.The analysis of data structure and algorithmOne of the most important ideas in many issues is that it is not enough to write a working procedur
Recently, some friends are working on Spider algorithms or in-depth data mining on webpages. However, when encountering complicated and complicated HTML pages, everyone is discouraged. It is difficult to obtain the corresponding data.
The oldest way is to use regular expressions to estimate the cost of tedious things and waste our precious time.
The second method is to use the open-source htmlparser package

frequency count on the ⅰ2 node is increased by 1, recorded as 2, and the frequency count of the node ⅰ4 is recorded as 1. Following the same procedure, the tree structure can be obtained after scanning all the transactions in the library.For the fp-tree that are built, the condition Fp-tree of each item is built sequentially from the bottom of the tree. First we found the node ⅰ5 in, found that the path to reach Ⅰ5 has two {ⅰ2,ⅰ1,ⅰ5:1} and {ⅰ2,ⅰ1,ⅰ3,ⅰ5:1}.The conditions for constructing the ⅰ5
