Lexicographically Smallest Replacement String Solution
Problem Statement
Given a string `text` and a dictionary `synonyms` where each key is a word and its corresponding value is a list of synonyms, find the lexicographically smallest string that can be formed by replacing the words in `text` with their synonyms from `synonyms`.
Constraints
- The input string s contains only alphanumeric characters and spaces.
- The dictionary wordDict can contain multiple synonyms for a single word.
- All the words in wordDict are unique and do not have any duplicates.
Time: O(N * M * K) Space: O(N + M + K)
