Well, the outputs don't look the same. Not sure if that's a mistype on your end.

Also, depending on the compiler, if you've specified 0x before an alphanumeric, it may treat it as byte code and thus not a string, the minute you start manipulating a string, it will always treat it as a string. Thus the ASCII to hex conversion issue.

Maybe try converting to binary afterwards and see what the 1s and 0s are.
