如何Use Morse Code
编码 and decode text in Morse code for education and communication exercises.
问题
你需要转换文本到 Morse 代码或 解码 Morse 代码回 到文本.
前置条件
- Knowledge 的 Morse 代码 symbols
- Understanding 的 dots 和 dashes
步骤
-
1. Learn the Morse code mapping
Each letter and digit maps to a sequence of dots (.) and dashes (-). A is .-, B is -..., etc. Letters are separated by a space, words by a larger gap (often represented as / or three spaces). Numbers and some punctuation also have mappings.
输入HELLO输出.... . .-.. .-.. --- -
2. Encode text to Morse
Convert each character to its Morse sequence using the mapping. Separate letters with a single space and words with a slash or multiple spaces. Uppercase the input first, as Morse is case-insensitive. Unknown characters can be skipped or marked with a placeholder.
输入SOS HELP输出... --- ... / .... . .-.. .--. -
3. Decode Morse to text
Split the Morse string on word separators first, then on letter separators. Map each Morse sequence back to its character. Handle ambiguous separators: a single space separates letters, a slash or multiple spaces separates words.
输入... --- ...输出SOS
预期结果
正确 Morse 代码编码或 解码的 输入文本.
常见错误
- Word boundaries lost in decoding
- Use a clear word separator (like /) between words. A single space between letters and / between words is the common convention.
- Lowercase letters not handled
- Morse code is case-insensitive. Uppercase the input before encoding, and output uppercase when decoding.
排障指引
- If decoding produces wrong characters, verify the Morse mapping table.
- Ensure consistent use of separators: one space between letters, / or three spaces between words.
安全限制
- Morse code is a simple substitution encoding with no security properties.
