Let's learn to write and read from memory, which is the Assembly way of making variables, saving data, and storing information in buffers.

Challenge Information: The goal is to make your memory profile be this exact layout, starting from your base address of the data segment. It may be 0x402000 or something else (although it seems the emulator doesn't have randomization turned on, so that's good for us to learn!)
