Solution: Word Break II
Explore how to solve the Word Break II problem using dynamic programming by decomposing a string into valid dictionary words. Understand the naive recursive approach and its inefficiencies, then learn to implement a tabulation method that builds solutions from substrings. This lesson helps you efficiently generate all possible sentences from a string by combining valid suffixes and prefixes, optimizing both runtime and memory usage.
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...
