摘　　要：提出了一种基于双指针的线性搜索算法,用于高效统计差值对的数量。该算法通过使用两个指针,一个从开始处向结束处移动,另一个从结束处向开始处移动,逐步缩小搜索范围并统计满足条件的差值对数量。算法具有较低的时间复杂度和空间复杂度,适用于处理大规模数据集。通过一系列实验验证算法的有效性,并对实验结果进行了详细的分析。实验结果表明,该算法在不同规模的数据集上都表现出良好的性能。此外,讨论了算法在不同领域的应用前景,并展望了未来可能的研究方向,为数据分析统计问题的解决提供了一个新的思路和方法。A linear search algorithm based on double pointer liner was proposed in this paper which was used to efficiently count the number of difference pair.This algorithm gradually narrowed the search range and counted the number of difference pair that meet the conditions by using two pointers,one moving from the beginning to the end and the other moving from the end to the beginning.The al-gorithm had lower time complexity and space complexity,and was suitable for processing large data sets.To verify the effectiveness of the algorithm,a series of experiments were carried out as well as the experimental results were analyzed in detail.The experimental results show that the algorithm performs well on datasets of different scales.In addition,the application prospects of algorithms in different fields were discussed and the possible research directions in the future are prospected.Through this re-search,a new idea and method for solving the problems in data analysis and statistics was provided.
