How to permanently reverse a string in Ruby

Overview

In Ruby, we use the reverse! method to permanently reverse a string.

Note: The reverse! method is different from the reverse method. reverse does not permanently modify a string, but reverse! does.

When we call the reverse! method on a string, the original string is modified and reversed. This means the characters in the string are reversed.

Syntax

str.reverse!

Parameters

• str: The string we want to permanently reverse.

Return value

This method returns a new string that is the reverse of the original.

Example

Explanation

• Lines 2 to 5: We create some strings.

• Line 9 to 12: We call the reverse method on the strings to permanently reverse the strings.

• Line 15 to 18: We print the permanently reversed strings to the console.
