String Rotate
Rotate text characters left or right with circular shift. Free online tool, no installation needed.
What is string rotation?
String rotation is a circular shift operation that moves characters from one end of a string to the other. For example, rotating \"hello\" right by 2 positions gives \"lohel\".
How does circular shift work?
In a circular shift, characters that fall off one end of the string wrap around to the other end. This preserves all characters while changing their positions.
What is the difference between left rotation and right rotation?
Left rotation moves characters from the beginning to the end, while right rotation moves characters from the end to the beginning. They are inverse operations of each other.
Is my text data safe?
Yes, absolutely. All text processing happens entirely in your browser. No data is sent to any server, ensuring complete privacy and security.
What is cyclic permutation in computer science?
Cyclic permutation is a mathematical concept where elements are rearranged in a circular manner. In string operations, it refers to rotating characters while maintaining their relative order.
Can I rotate text by a specific number of positions?
Yes, you can specify any number of positions to rotate. The tool automatically handles values larger than the string length using modulo arithmetic.
Does this tool work with Unicode and special characters?
Yes, the tool supports Unicode characters including emojis, accented letters, and characters from various writing systems like Chinese, Japanese, and Arabic.
What are common use cases for string rotation?
String rotation is used in cryptography (Caesar cipher), data encoding, algorithm testing, string matching algorithms (like Booth\'s algorithm), and puzzle solving.
Is there a limit on text length?
There is no hard limit. The tool processes text entirely in your browser, so the maximum length depends on your device\'s available memory.
Can I use this tool offline?
Once the page is loaded, all processing happens locally. However, you need an initial internet connection to load the tool\'s resources.
How to Use String Rotate
Shift the characters of your text left or right in a circular motion, instantly, right in your browser. Your text never leaves your device.
- Enter the text you want to rotate into the input area.
- Type the number of positions to move into the Steps: field, for example 3.
- Pick Right to shift characters toward the end of the text or Left to shift them toward the start.
- Enable Multi-line to rotate every line independently instead of treating the whole text as one string.
- Copy the rotated output and paste it wherever you need it.
Rotating by exactly the length of the text gives back the original, so keep Steps: smaller than your string length for a visible change.
