# Keyword Analysis & Research: finding time complexity of algorithms

## Frequently Asked Questions

How to calculate time complexity?

Time complexity of different loops is equal to the sum of the complexities of individual loop. Therefore, Time complexity = O(m)+O(n)

What is the worst case time complexity for this algorithm?

The worst-case time complexity for the contains algorithm thus becomes W ( n ) = n. Worst-case time complexity gives an upper bound on time requirements and is often easy to compute. The drawback is that it’s often overly pessimistic. See Time complexity of array/list operations for a detailed look at the performance of basic array operations.

How to calculate the running time of an algorithm?

to calculate the running time of an algorithm, First of all, we calculate how many operators and inputs are there in the algorithm. so as to shows in the image, the algorithm has one input and three operators. one is an assignment, one is the comparison and the other one is the arithmetic operator.
