# Time and Space Complexity

## Assymptotic Notations

- To get an idea of notations like Big-Oh, Omega and Theta, it is recommended to watch this video, by Abdul Bari.

## Finding the time complexity

- You should be able to find out the time complexity of a given code snippet. You can watch this video for this.

## Checking whether your solution will pass the time limits

- Go through this tutorial on hackerearth. You must be able to find out, if your solution is fast enough, to pass the time limit constraints.

##### tip

Approximately, 10^{7}-10^{8} operations are performed in 1 second. Always use this information, to estimate whether your solution will be able to pass the time limits, before writing any code.
