Time Complexity

Time complexity refers to the amount of time it takes for a program's algorithm to complete its task, relative to the size of the input provided to the algorithm. It's a measure of an algorithm's efficiency, and is typically expressed using Big O notation, which describes the upper bound of the algorithm's time complexity.

Why Learn Time Complexity?

Understanding time complexity is crucial for several reasons:

• Algorithm Optimization: Time complexity analysis can help you identify inefficiencies in your algorithms, allowing you to optimize them for faster execution.
