将音频文件按一定的时间间隔分割成多个小的音频片段,然后对每个小片段进行相同的处理再合并结果即可得到大片段的处理结果。 归并排序 将一个无序的数据集分成两个(或更多)较小的部分,最终可将子集排序合并成有序集合。 def merge_sort(arr): if len(arr) > 1: mid = len(arr) // 2 left_half = arr[:...

戴克斯特拉算法(Dijkstra’s algorithm)是由荷兰计算机科学家艾兹赫尔·戴克斯特拉提出。迪科斯彻算法使用了广度优先搜索解决非负权有向图的单源最短路径问题,算法最终得到一个最短路径树。该算法常用于路由算法或者作为其他图算法的一个子模块。 该算法的输入包含了一个有权重的有向图G,以及G中的一个来源顶点S。我...

2. Sorting: While binary search itself is not a sorting algorithm, it can be combined with sorting algorithms like merge sort or quicksort to efficiently search for elements in sorted arrays. 3. Computer Science: Binary search serves as a foundational concept in computer science education, provid...
A naive algorithm of O(n2) is trivial. You MUST do better than that. Example: Given nums = [-2, 5, -1], lower = -2, upper = 2, Return 3. The three ranges are : [0, 0], [2, 2], [0, 2] and their respective sums are: -2, -1, 2. ...
2.If a problem is in NP, it cannot be solved by a deterministic algorithm in polynomial time.（）如果一个问题属于NP，它将不能被一个时间复杂度为多项式的确定性算法解决。（）3.The in-order depth-first traversal of a binary search tree (BST) produces elements in descending order. （）二叉...
