Understanding the Replace Words Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
In English, we have a concept called root, which can be followed by some other word to form another longer word - let's call this word derivative. For example, when the root "help" is followed by the word "ful", we can form a derivative "helpful". Given a dictionary consisting of many roots and a sentence consisting of words separated by spaces, replace all the derivatives in the sentence with the root forming it. If a derivative can be replaced by more than one root, replace it with the root that has the shortest length. Return the sentence after the replacement.
