sw33tLie on 10:02 PM 03/25/2019: Yes patching is allowed...be creative!
You just have to force the console to show the right thing.

Nice solution, really well written. Your method works for sure and it's correct, but i would have done it in a different way.
If you check the assembly you will see that the right subroutine that shows the correct string is basically an unreferenced function. I would have patched the call instruction from the main() function to call it instead of the wrong string subroutine.
That said, thanks for submitting it anyway :)
