running time examples In this guide you have learned what time complexity is all about how performance is determined using the Big O notation and the various time complexities that exists with examples You can learn more
1 Overview In this tutorial we ll talk about what Big O Notation means Then we ll review a few examples to investigate its effect on running time 2 The Intuition of Running Time It is convenient to use a function T n to represent the number of units of time taken by a program or an algorithm on any input of size n We shall call T n the

Examples of O 1 constant runtime algorithms Find if a number is even or odd Check if an item on an array is null Print the first An important thing to note is that the running time when using big O notation does not directly equate to time as we know it e g seconds milliseconds microseconds etc Analysis of running times
For example let s say you have an algorithm that looks for a number in a list by searching through the whole list linearly These are the possible running times Worst case Is the Time Complexity of an Algorithm Code the same as the Running Execution Time of Code The Time Complexity of an algorithm code is not

Let s explore each time complexity type with an example 1 O 1 Where an algorithm s execution time is not based on the input size n it is said to have constant time complexity with order O 1 Whatever be Simple search s run time grows exponentially as the list of entries increases This is why knowing how the running time increases in relation to a list size is so important And this is exactly where Big O
Some examples of the running time would be n 2 2n n 3 3n 2 n logn etc Having this knowledge of running time if anyone asks you about the running time of your program you would say the running time of my Running time is often shortened to runtime and is also known as the efficiency or performance of a program In this chapter we ll study a formal approach to analysing

running time examples - The fastest possible running time for any algorithm is O 1 commonly referred to as Constant Running Time In this case the algorithm always takes the same amount of time to execute regardless of the input size This is the ideal runtime for an algorithm but it s rarely achievable
