Definition

The measure of the amount of time an algorithm takes to complete as a function of the size of the input, often expressed using Big O notation to describe the upper bound of an algorithm's performance

Summary

Time complexity is a fundamental concept in computer science that helps us evaluate the efficiency of algorithms. By understanding how the runtime of an algorithm grows with input size, we can make informed decisions about which algorithms to use in different scenarios. This knowledge is crucial for developing scalable and efficient software applications. In this study of time complexity, we explored key concepts such as Big O notation, worst-case and best-case scenarios, and the importance of analyzing algorithm efficiency. By applying these concepts, learners can better understand the performance implications of their code and make choices that enhance user experience and resource management.
