Where's the problem? Just open your hex editor, type the data in, and hit save.

Solution 1

This smells of homework, so no code!
But it's really easy...

1 Create a buffer big enough to hold the output bytes: length of input / 2 should do it.
2 Convert a pair of hex digits to a unsigned byte, and add the byte to a buffer. Repeat until all pairs are used up.
3 Write the buffer to a file in binary mode.
