# 11. Gray to Binary equivalent

The problem can be found at the following link: [Question Link](https://www.geeksforgeeks.org/problems/gray-to-binary-equivalent-1587115620/1)

## My Approach

To convert a Gray code to binary, we can use bitwise XOR operations. The process involves iterating through each bit of the Gray code, and at each step, XOR-ing it with the previously processed bit. This results in the binary representation of the given Gray code.

## Time and Auxiliary Space Complexity

* **Time Complexity** : `O(log n)`, where n is the input number.
* **Auxiliary Space Complexity** : O(1).

## Code (C++)

```cpp
class Solution {
public:
    int grayToBinary(int n)
    {
        int ans = 0;
        while(n > 0)
        {
            ans = ans ^ n;
            n = n >> 1;
        }
        return ans;
    }
};
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gl01.gitbook.io/gfg-editorials/2024/04-2024-april-8/11-gray-to-binary-equivalent.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
