String Reverse

String reversal mirrors text along a horizontal axis. Character reversal transforms "hello" into "olleh" — every symbol flips position including spaces and punctuation. Word order reversal keeps each word intact but swaps their sequence: "hello world" becomes "world hello". Line reversal operates on multiline text, flipping each row independently or reversing the line order itself.

Reversal appears in palindrome puzzles, encoding exercises, bioinformatics (reverse complement DNA sequences), and programming interview questions. Developers test string manipulation functions by comparing output against a known reversed reference. Designers create mirror effects for logos and stylized social media text.

Unicode characters including emoji may consist of multiple code points; proper reversal respects grapheme clusters so skin-tone modifiers and combined characters stay intact rather than splitting into broken glyphs. Multi-byte characters reverse as complete units, not individual bytes.

Combine with case converter for styled reversed text and with binary converter to inspect how reversed strings change encoded byte sequences. The text repeater duplicates reversed patterns for stress testing input fields with palindrome-like data.

Whether you are solving a cipher, testing your application's handling of reversed input, or creating a visual effect, string reversal applies a simple transformation with surprisingly many practical and playful uses.
