Use this Big O Calculator tool to quickly determine the efficiency and complexity of your algorithms.

## Big O Notation Calculator

This calculator helps in understanding the time complexity of algorithms in terms of Big O Notation. You can enter a value for *n* and select the algorithm’s time complexity, and the calculator will evaluate the complexity’s value (or an approximation) based on the input size.

### How to Use the Calculator

To use the calculator, follow these steps:

- Input a positive integer value for
*n*(size of the input). - Select the time complexity from the dropdown menu (e.g., O(n), O(n^2)).
- Click the “Calculate” button to get the result.

### Understanding the Results

The result gives you the estimated number of operations required by an algorithm with the chosen complexity and input size. For instance, if you select O(n) and enter 5, it computes to 5, suggesting an algorithm linearly grows with input size.

### Limitations

The calculator provides a rough estimate and does not account for constants and lower-order terms that are disregarded in Big O analysis. It cannot evaluate complexities for very large values of *n*, such as factorial time complexity (O(n!)), where n is very large because it could potentially cause a stack overflow due to recursion limits.
