Coding tips

💻

String reversal is a classic coding interview question. Test your implementation against this tool's output — it correctly handles Unicode and emoji.

💡

A common bug: reversing bytes instead of characters. "hello 😊" reversed should be "😊 olleh", not garbled emoji. This tool uses code points correctly.

🧩

"Flip Lines" mode reverses each line independently — useful for testing multi-line string handling and line-by-line processing algorithms.

🔢

Test with edge cases: empty string, single character, palindrome, emoji, accented characters. Verify your algorithm handles all of them.
