Can I post a remade version of a code that already exists?

[ComputerBot2016]

My code doesn’t hook onto an address from Joshua’s code. What I meant was that in order to find the function used by my code, I had to BP some of the addresses in his code to see how his version worked. I’m not using any of his addresses in the code itself, however I still feel that he should get credit, since without his code, it would’ve been harder to make my one.
