Solution: Word Break II
Explore the dynamic programming approach to solve the Word Break II problem by breaking a string into valid dictionary words. Understand how to use a bottom-up method, create a lookup table for prefixes, and efficiently generate all possible sentence combinations while managing time and space complexity.
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...
