How do you find the time complexity of an online algorithm?
For any loop, we find out the runtime of the block inside them and multiply it by the number of times the program will repeat the loop. All loops that grow proportionally to the input size have a linear time complexity O(n) . If you loop through only half of the array, that’s still O(n) .
What is the best time complexity algorithm?
Time Complexities of all Sorting Algorithms
| Algorithm | Time Complexity | |
|---|---|---|
| Best | Worst | |
| Selection Sort | Ω(n^2) | O(n^2) |
| Bubble Sort | Ω(n) | O(n^2) |
| Insertion Sort | Ω(n) | O(n^2) |
What is average best and worst-case complexity?
Best case is the function which performs the minimum number of steps on input data of n elements. Worst case is the function which performs the maximum number of steps on input data of size n. Average performance and worst-case performance are the most used in algorithm analysis.

What is the expected time complexity of online tests?
Sometimes we have the information we need about the expected time complexity (for example, Codility specifies the expected time complexity), but sometimes we do not. The time limit set for online tests is usually from 1 to 10 seconds. We can therefore estimate the expected complexity.
What is the best book to learn about computer algorithms?
The book offers treatment of dynamic programming and greedy algorithms and a new notion of edge-based flow. The learning material also provides many exercises, problems, and solutions. Algorithms is a book written by Robert Sedgewick and Kevin Wayne. This book covers all the most important computer algorithms currently in use.
