Complexity analysis is a technique used to evaluate the efficiency of an algorithm in terms of time and space resources required to execute it. It helps in comparing different algorithms and determining their performance based on input size.
Asymptotic Notations
Asymptotic notations are mathematical tools used to describe the running time of an algorithm as a function of the input size. The most common notations are:
Big O Notation (O): Represents the upper bound of the running time, describing the worst-case complexity of an algorithm. For example, binary search has a time complexity of O(log n).
Omega Notation (Ω): Represents the lower bound of the running time, describing the best-case complexity of an algorithm.
Theta Notation (Θ): Represents both the upper and lower bounds, describing the average-case complexity of an algorithm.
Types of Complexity
Constant Complexity (O(1)): The running time does not depend on the input size. Example:
