endianness

  • Description: Know of little and big endian?
  • Difficulty: Easy

🔎 Solution​

This challenge provides a random string, and your task is to determine its representation in both Little Endian and Big Endian formats. Start by encoding the string into its hexadecimal representation. For example, the string qlqvt becomes: 71 6c 71 76 74.
In Little Endian, the least significant byte is stored first (at the lowest memory address), so the byte order is reversed. The resulting representation would be: 74 76 71 6c 71.

Word: qlqvt
Enter the Little Endian representation: 7476716c71
Correct Little Endian representation!

In Big Endian, the most significant byte is stored first (at the lowest memory address), so the byte order remains as-is: 71 6c 71 76 74.

Enter the Big Endian representation: 716c717674
Correct Big Endian representation!

Successfully deriving both formats will bring you one step closer to solving the challenge.

Congratulations! You found both endian representations correctly!
