Solution: Word Break II

Explore how to apply dynamic programming to the Word Break II problem by breaking a string into valid dictionary words. Learn to optimize recursive solutions with tabulation, understand the process of constructing all valid sentences, and analyze the time and space complexity involved.

Statement

You are given a string, s, and an array of strings, wordDict, representing a dictionary. Your task is to add spaces to s to break it up into a sequence of valid words from wordDict. 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:

  • 11 \leq s.length 20\leq 20 ...
