We begin this lecture with an overview of recurrence relations, which provides us with a direct mathematical model for the analysis of algorithms. We finish by examining the fascinating oscillatory behavior of the divide-and-conquer recurrence corresponding to the mergesort algorithm and the general ...
nlogn 线性对数阶算法,这种时间复杂度源于一种特定的算法设计技巧叫分治法,如归并排序(mergesort),后续几周内会有介绍 算法中有两层for循环(如 2-SUM),算法的运行时间是平方阶的,和N^2成正比,当输入翻倍后,运行时间增大4倍 三层loop(如 3-SUM),运行时间就是立方阶的,与N^3成正比,当输入翻倍后,运行时间...

Asymptotic notations are the mathematical notations used to describe the running time of an algorithm when the input tends towards a particular value or a limiting value. For example: In bubble sort, when the input array is already sorted, the time taken by the algorithm is linear i.e. the...
