This article will explain in detail what is related to the execution efficiency of the algorithm. The content of the article is of high quality. Therefore, Xiaobian shares it with you as a reference. I hope you will have a certain understanding of relevant knowledge after reading this article.

The execution efficiency of an algorithm is related to "space complexity" and "time complexity." Space complexity is based on the length of the memory unit occupied by the program written according to the algorithm during execution, and time complexity is the length of the time spent by the program written according to the algorithm during execution.

algorithm complexity

There are two main indicators to measure and compare algorithms:

Space complexity S(n): the length of memory cells occupied by a program written according to an algorithm when executed

Time Complexity T(n): The length of time a program written according to an algorithm takes to execute

Analyze general algorithm efficiency:

Worst-case complexity $T_{worst}$(n)

Average complexity $T_{avg}$(n)

About what and algorithm execution efficiency related to share here, I hope the above content can be of some help to everyone, you can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
