How do I reverse a string using XOR?

Algorithm to Reverse String Without Temporary Variable

1. Store start index in low and end index in high.
2. Here, without creating a temp variable to swap characters, we use xor(^).
3. Traverse the input string “s”.
4. Swap from first variable to end using xor.
5. Return the final output string.

How do u reverse a string?

Strings can be reversed using slicing. To reverse a string, we simply create a slice that starts with the length of the string, and ends at index 0. The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward).

How to use reverse a string in C?

To demonstrate the reverse a string in c programming, we are going to use For Loop , While Loop, Functions, and Pointers. This reverse a string in c program allows the user to enter any string or character array.
