So I have this client and server code, and basically the client either chooses B for binary or H for Hex when they choose. The user inputs an integer, and the server converts it to either Hex or Binary depending on what the user chose. The code I provided seems to have an error. Every time I chose Hex or Binary, it gives me the wrong answers. For example, I chose H and input $17,$ it gives me the output F$,$ which is incorrect. Another example, when I chose B and input $100,$ it gives me $11.$ And so on$.$ Help me fix this logical error, please
