在数据库中发现频繁模式和关联规则是数据挖掘领域的最基本、最重要的问题。大多数早期的研究采用了类似Apriori算法的产生候选级并测试迭代的途径代价是昂贵的，尤其是挖掘富模式和长模式时，Jiawei Han提出了一种新颖的数据结构FP_tree,及基于其上的FP_growth算法，主要用于有效的进行长模式与富模式的挖掘.本文在讨论了FP_growth算法的基础上，提出了用Visual C++实现该算法的方法，并编写了算法的程序。-found in the database model and the frequent association rules is the area of data mining the most fundamental and important issues. Most of the early studies used a similar Apriori algorithm for the selection of candidates and test-iterative way was costly, particularly mining the rich patterns and long model, Jiawei Han proposed a novel data structure FP_tree and on the basis of their FP_growth algorithm used effectively the model for long and rich patterns of excavation. This paper discussed the FP_growth algorithm on the basis of the Visual C of the algorithm, and the preparation procedure of the algorithm.

Goertzel基本算法在每次采样后立即进行处理，在每个第N次采样进行一次音调检测。在采用FFT算法时，我们要对成块的采样进行处理，但这并不意味着必须按块来处理数据。数字处理的时间很短，因此如果每次采样都存在一次中断，那么这些数字处理完全可以在中断服务程序(ISR)内完成。或者，如果系统中存在采样缓存，那么可以持续采样，然后进行批处理。-Goertzel basic algorithms in each sample immediately after processing, in each of the first N sub-samples to conduct a tone detection. In the use of FFT algorithms, we would like to be processed into a block of samples, but this does not mean that must block processing the data. Digital processing time is very short, so if an interrupt for each sample are present, then the digital processing is fully able to interrupt service routine (ISR) to complete. Or, if the system exists in sample buffer, you can continue to sample, and then batch.

递归计算众数，重数，输入一个整形数组，用递归计算数组中出现次数最多的数（众数）以及出现次数（重数）。-Recursive calculation mode, re-number, enter an integer array, with the recursive computation of the array appear in the highest number of number (plural), and the number of occurrences (multiplicity).
