WebOct 24, 2024 · Time complexity is the amount of time taken by a set of codes or algorithms to process or run as a function of the amount of input. For insertion sort, the time … WebIn computer science, the time complexity of an algorithm is expressed in big O notation. Let's discuss some time complexities. O (1): This denotes the constant time. 0 (1) usually means that an algorithm will have constant time regardless of the input size. Hash Maps are perfect examples of constant time. O (log n): This denotes logarithmic time.
