-| -----------|-------------- | ---------------------------- | ----------------------------- | ------------------------------- |
-|Constant |**O(1)**| 1 | 1 | 1 |
-|Logarithmic |**O(log N)**| 3 | 6 | 9 |
-|Linear |**O(N)**| 10 | 100 | 1000 |
-|n log(n) |**O(N log N)**| 30 | 600 | 9000 |
-|Quadratic |**O(N^2)**| 100 | 10000 | 1000000 |
