Solution: Word Break II
Explore dynamic programming to efficiently solve the Word Break II problem. Understand how to build a table of valid sentence sequences from a string using a dictionary, optimize recursive methods with memoization, and handle overlapping subproblems for better performance.
Statement
You are given a string, s, and an array of strings, word_dict, representing a dictionary. Your task is to add spaces to s to break it up into a sequence of valid words from word_dict. We are required to return an array of all possible sequences of words (sentences). The order in which the sentences are listed is not significant.
Note: The same dictionary word may be reused multiple times in the segmentation.
Constraints:
-
s.length...
