Reverse Strings for Coding Practice
Verify your string reversal algorithms and test edge cases with emoji, Unicode, and multi-byte characters.
Coding tips
String reversal is a classic coding interview question. Test your implementation against this tool's output β it correctly handles Unicode and emoji.
A common bug: reversing bytes instead of characters. "hello π" reversed should be "π olleh", not garbled emoji. This tool uses code points correctly.
"Flip Lines" mode reverses each line independently β 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.
