Inspired by this article. Neat tricks for speeding up integer computations.
Note: cin.sync_with_stdio(false); disables synchronous IO and gives you a performance boost.
If used, you should only use cin for reading input
(don't use both cin and scanf when sync is disabled, for example)
or you will get unexpected results.
x = x << 1; // x = x * 2
| 1) A Bloom filter is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set | |
| For example, checking availability of username is set membership problem, where the set is the list of all registered username. | |
| The price we pay for efficiency is that it is probabilistic in nature that means, there might be some False Positive results. | |
| False positive means, it might tell that given username is already taken but actually it’s not. | |
| 2) The base data structure of a Bloom filter is a Bit Vector |

| The rate at which the running time increases as a function of input is called rate of growth | |
| Worst case | |
| ○ Defines the input for which the algorithm takes a long time (slowest time to complete). | |
| ○ Input is the one for which the algorithm runs the slowest. | |
| ○ Big O notation is a convenient way to express the worst-case scenario for a given algorithm | |
| Best case |

| The difference between these two, is that devDependencies are modules which are only required during development. | |
| while dependencies are modules which are also required at runtime. |
| Transient objects are always different; a new instance is provided to every controller and every service. | |
| Scoped objects are the same within a request, but different across different requests. | |
| Singleton objects are the same for every object and every request. | |
