Understanding character mappings.
Under the ASCII encoding standard, every readable character, symbol, or command maps to a specific number between 0 and 127.
For example, capital letter 'A' is index 65, lowercase 'a' is 97, and the space character is 32.
Step-by-step example.
Convert the string "Hi" into decimal:
- Find the decimal index for character 'H': 72.
- Find the decimal index for character 'i': 105.
- Concatenate with a space for readability: 72 105.
