###### Question 2: The LCD is a 1602 (16 columns × 2 rows). What would happen if you could somehow put a 20-character string in memory? Would the LCD display all 20, or only the first 16?
###### Question 3: If you wanted to combine both hacks from Exercise 1 (changing strings) AND the Week 7 tutorial hacks (changing FAV_NUM and OTHER_FAV_NUM), could you do all patches in a single `.bin` file? What offsets would you need to modify?
###### Question 3: If you wanted to combine the string hacks from Exercise 1 (changing both LCD lines) AND a hypothetical numeric hack (e.g., changing the `movs r1, #42` encoding at offset `0x28E`), could you do all patches in a single `.bin` file? What offsets would you need to modify?
###### Question 4: Besides LCD text, what other strings could you patch in a real-world embedded device to change its behavior? Think about Wi-Fi SSIDs, Bluetooth device names, HTTP headers, etc.
