time complexity definition

Definition of Time Complexity in C++

The time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the input. It is commonly expressed using big O notation. The time complexity of an algorithm is a theoretical measure and is typically expressed in terms of the input size, denoted by "n." The time complexity provides an upper bound on the running time of an algorithm, allowing programmers and analysts to compare the efficiency of algorithms and to make informed decisions about algorithm selection.
