The main idea finding the flag is to read the question properly and interpret.

Step-1:

After we read the given message:

Meet ROXy, a coder obsessed with being exclusively the worlds best hacker. She specializes in short cryptic hard to decipher secret codes. The below hex values for example, she did something with them to generate a secret code, can you figure out what? Your answer should start with 0x.

0xc4115 0x4cf8

Step-2:

Meet ROXy - This should give us a simple idea that we have to XOR the 2 given Hex numbers.

Step-3:

So I tried it online here:

Note: Do not forget 0x before flag.

Step-7:

Finally the flag becomes: CTFlearn{0xc0ded}
