Problem:
Determine the bit representation of a byte, such as getting "00000001" from byte(1).
Solution:
There are two approaches to extracting bit representations:
Visual Representation Using Formatting:
Bitwise Operations for Mathematical Operations:
Example:
To find the bits of byte(13):
<code class="go">fmt.Print(13 & 1) // Output: 1 fmt.Print(13 & 2) // Output: 0 fmt.Print(13 & 4) // Output: 4 fmt.Print(13 & 8) // Output: 8</code>
This demonstrates that the bit representation of 13 is "00001101".
Additional Note:
For calculating Hamming distance between bytes, the provided code uses bitwise operations to compare each bit individually. The function counts the number of mismatched bits and returns the distance.
