Given an array of integers `nums` and an integer `target`, return indices of the two numbers such that they add up to `target`. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order.
Write a function that reverses a string. The input is given as a string. Do not update the original string. You must do this by returning another string.
In web applications, displaying user-generated content without sanitizing it can lead to security vulnerabilities such as Cross-Site Scripting (XSS). Write a function that takes a string of HTML and returns a sanitized version where all tags and attributes are removed, leaving only plain text.
