Solution: Word Break II
Explore how to apply dynamic programming to solve the Word Break II problem by breaking a string into all possible sentences using dictionary words. Understand the transition from a naive recursive approach to an optimized tabulation method, improving time and space efficiency. This lesson guides you through building a solution that handles overlapping subproblems and constructs valid sentences from string prefixes.
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...
