reverse words Algorithm
A reverse proxy in such cases could transform HTTPS requests into HTTP requests, buffer incoming requests based on the load of the" shielded" server(s), handle cookies / session data, or transform one request into multiple requests and then synthesize the responses, among other possibility. Quite often, popular web servers use reverse-proxying functionality, shielding application frameworks of weaker HTTP capability.
/*
* Given a string, you need to reverse the order of characters in each word within a sentence
* while still preserving whitespace and initial word order.
*
* Example:
* Input: She loves chocolate
* Output: ehs sevol etalocohc
*
* Approach:
* Use two indices to figure out non-whitespace characters, and reverse
* the portion.
