Problem Brief

Clean Up Captions

As a TikTok developer, you're working on a project to clean up captions and optimize storage. With millions of captions and hashtags circulating the platform, your task is to detect any overlap between captions on the for_you feed and the following feed. But it's not just about finding common words or hashtags; you need to identify any common substring between the two!

You are given two lists of captions — one from the for_you feed and another from the following feed. For each corresponding pair of captions, your job is to check if any substring appears in both captions. If a common substring is found, you should output "YES"; otherwise, output "NO."

Function Description

Complete the function optimizeStorageByCleaning in the editor.

optimizeStorageByCleaning has the following parameter(s):

String for_you[n]: an array of strings
String following[n]: an array of strings

Returns

String answers[n]: An array of strings where each element is either "YES" or "NO". "YES" indicates that a common substring exists between the corresponding logs in for_you and following, while "NO" indicates that no common substring exists.
